Objectives
The lack of bridges between theory and experiment is one of the major roadblocks impeding the
discovery and development of materials and devices able to respond by design to the needs of specific
applications in harsh environments. For instance, radiation-induced defects and radiation-enhanced diffusion
of metal contact materials in CMOS-based image sensors degrade their performances and drastically reduce
their efficiency (recombination, capture and/or metastable emission centers).

The objectives of this WP are:

1) to define an experimental schema together with its corresponding model counterpart to ensure that the
theoretical picture accurately represents the specificities of the experiment.

2) to develop a modeling framework for Capacitance Transient Spectroscopy (CTS) that enables meaningful
comparison between experimental and theoretical data.

3) to identify specific defects in well-understood semiconductors such as Si, Ge, GaN, GaAs and SiC that
can be exhaustively modeled and measured for mutual comparison of results.

4) to identify the atomic scale mechanisms responsible for the radiation-induced degradation of typical metal-
semiconductor junctions (for instance Cu or Pd on Si) including defect enhanced diffusion.

Objectives
PbS/CdS/ITO and CdTe/CdS/ITO multilayer photovoltaic cells are ubiquitous in many
applications, from sensors to solar cells. Their physical and optical properties can be tuned by adjusting the
thickness of the various layer and can be modified by irradiating them.

The objectives of this WP are:

1) to synthesize PbS, CdS, CdTe, and ITO layers, and PbS/CdS/ITO and CdTe/CdS/ITO multilayers via RF
Sputtering and contribute to understanding the growth process

2) to determine crystal structure, physical and chemical properties of the individual layers as a function of
thickness, and the structure and properties of the interfaces in PbS/CdS/ITO and CdTe/CdS/ITO.

3) to determine the properties of point defects in multilayer samples before and after gamma, p+ , and alpha
irradiation.

4) to determine the physical and chemical properties of irradiated samples.

Objectives
The main goal of this WP is to study the effects of irradiation on nanostructured materials, both
single-metal and multi-metal (high-entropy alloy – HEA) nanoparticles in solution and embedded in a
substrate, for possible use as radiation-resistant materials. This WP will use swift heavy ion and ultrashort
laser pulse irradiation, and computational modelling.

The objectives of this study are:

1) to improve our understanding of damage mechanisms of metallic nanoparticles,

2) to take advantage of some of those effects to modify the nanostructures in a controlled way, with the
goal of improving their optical properties,

3) to design radiation-resistant nanostructured materials.

Objectives
The aim of this WP is to investigate, at a fundamental and experimental levels, the interaction of photons
and electrons with dosimetric materials in the low-energy regime, which is governed by quantum
mechanics.

The objectives of this WP are:

1) to elucidate the characteristics of the interaction of ionizing radiation with the materials used in radiation
dosimetry, at the microscopic level, i.e., the defect structure created upon radiation;

2) to determine possible effects or damage and consequently establish an accurate relationship between the
energy deposited and the response of various dosimetric materials;

3) to evaluate the dose delivered to patients in modern radiotherapy fields, and in low-energy photon beams
used in radiodiagnostic studies.

Objectives
The knowledge of biological effects of proton irradiation is of crucial importance in Proton
Therapy (PT) for clinical dose prescription (Tumor Control Probability TCP) and for Normal Tissue
Complication Probability (NTCP). However, they depend on many variables like p + incident energy, tissue
cells type, penetration depth, dose rate (FLASH-PT), and endpoint, and are thus not well understood. Various
aspects of radiation effects will be considered, from projectile-biological molecule collisions to ion track
simulations and radiobiological experiments.

The objectives of this WP are:
1) to conduct theoretical and experimental studies of the impact of different radiation qualities on cells, with
focus on both nuclear and membrane damage.

2) to conduct theoretical and experimental studies of the impact of different radiation qualities on cells, with
focus on both nuclear and membrane damage.

3) to improve the cross sections introduced in Monte Carlo codes for particle tracks to obtain a more reliable
calculation of energy deposition at the scale of biomolecules

4) to investigate different hypothesis for FLASH effect for photon and proton beams

5) to improve the evaluation of TCP and NTCP for clinical PT and space radiation radioprotection

Objectives
Radiolytic hydrogen gas yields in oxide-water systems depends dramatically on the type of oxide, crystal
structure, and the structure of the oxide/water interface. The mechanism proposed is exciton creation in the
oxide, transfer to the water, and reaction of the exciton with water or OH, leading to cleavage and H release.
In this WP we will study excitons in three different oxides, ZrO2 , CuO, and ZnO, for which there are detailed
experimental data on H2 yields, and increase, decrease, and do not modify the H2 yield.

The objectives of this WP are:

1) to obtain the exciton binding energy and wave function for oxide and water bulk and surface, and for the
oxide-water interface, for different crystal structures and oxide surfaces

2) to identify which configurations are more favorable for the exciton to transfer to the water

3) to determine the relationship between excitons, O-H bond cleavage, and H2 yield.

Objectives
One of the main activities in MAMBA is the secondment of PhD students and postdoctoral
fellows between MS/AC and TC. This, however, is not sufficient to create a sense of a community under the
overarching philosophy.
In order to reinforce the meaning of the MAMBA project and how it stretches over
all the research work packages, we have set the following specific objectives under training and networking:

1) to train the ESRs in state-of-the-art computer modelling and experimental irradiation platforms and analysis
over a wide range of methods;

2) to generate awareness about experiment in the community of modellers, and vice versa;

3) to bring the ERs and ESRs under a common umbrella, thus creating a community of theorists and
experimentalists who share a common research interest in the field of materials irradiation;

4) to create the conditions for intra-community networking, while providing opportunities for networking
with scientists and engineers not directly involved in this group;

5) to generate the conditions for cross-pollination between the various research WPs.

Objectives
The overarching goal of MAMBA is to avail of international exchanges to conduct simulation-led, predictive,
materials design by closely interacting with experimental partners in a synergistic way. This, however, would
fall short of fully accomplishing its goal without a consistent outreach effort.

The objectives of this WP are:
1) to engage with the scientific community and engineers to explore possible technological impacts of the research.

2) to engage with the general public to show how scientific research is being used for the
benefit of society at large. It is particularly important to reach the new generations and attract them towards
STEM subjects in particular the growing discipline of modelling and computer simulation.

3) to promote the activities of MAMBA and the MSCA-SE program through the UNESCO TWAS and ICTP
outreach channels, thus increasing the awareness of developing countries on the opportunities that
the MSCA-SE program might open, thus reducing the “two worlds” commonly accepted idea.
A borderless science can help or drive the change for a borderless world.
