Various damage mechanisms in carbon and silicon materials under femtosecond x-ray irradiation
Nikita Medvedev, Viktor Tkachenko, Vladimir Lipp +2
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 approach,…
Electron-ion coupling in semiconductors beyond Fermi's golden rule
Nikita Medvedev, Zheng Li, Victor Tkachenko +1
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 coef…
Thermal and nonthermal melting of silicon under femtosecond x-ray irradiation
Nikita Medvedev, Zheng Li, Beata Ziaja
As it is known from visible light experiments, silicon under femtosecond pulse irradiation can undergo the so-called 'nonthermal melting' if the density of electrons excited from t…
