Silicon quantum dots (SiQDs) hold great promise for many future technologies. Silicon is
already at the core of photovoltaics and microelectronics, and SiQDs are capable of efficient …

We propose a systematic analysis method for identifying essential parameters in various
linear and nonlinear response tensors without which they vanish. By using the Keldysh …

Based on high quality surgery and scientific data, scientists and surgeons are committed to
protecting patients as well as healthcare staff and hereby provide this Guidance to address …

In this paper, we discuss the validity of the band structure concept in silicon nanocrystals a
few nanometers in size. We introduce a general method which allows reconstruction of a …

Crystalline semiconductors may exist in different polytypic phases with significantly different
electronic and optical properties. In this paper, we calculate the electronic structure and …

We review the results of our research on damage mechanisms in materials irradiated with
femtosecond free-electron-laser (FEL) pulses. They were obtained using our hybrid …

Embedded Si and Ge nanocrystals (NCs) in wide band-gap matrices are studied
theoretically using an atomistic pseudopotential approach. Small clusters to large NCs …

This is the user manual for the hybrid code XTANT-3, simulating intense femtosecond X-ray
irradiation of matter. The code combines a few models into one with feedbacks: transport …

The event-by-event Monte Carlo code, TREKIS, was recently developed to describe
excitation of the electron subsystems of solids in the nanometric vicinity of a trajectory of a …

In the present work, a theoretical study of electron-phonon (electron-ion) coupling rates in
semiconductors driven out of equilibrium is performed. Transient change of optical …
