Monte Carlo Simulation Of Hole Transport And Terahertz Amplification In Multilayer Delta Doped Semiconductor Structures
… developed. All possible intra- and inter-subband scattering rates are theoretically calculated for Ge, Si, and GaAs. A far-infrared laser concept based on intersubband transitions of holes in p-type periodically delta-doped semiconductor films is studied using numerical Monte-Carlo simulation of …

Interaction of non-equilibrium phonons with electron-hole plasmas in germanium
… A full Boltzmann equation solution including carrier-carrier scattering is necessary to explain the results. Uniaxial stress is used to tune the Fenni energy of the EHL along certain directions and the corresponding restriction on the allowed scattering (the 2kf-cutoff) is observed.. In the …

Optoelectronics of graphene-based Van der Waals heterostructures
… this vertical charge transfer and in-plane carrier-carrier scattering in different regimes. In Chapter 7, I will briefly summarize collaborated work with Prof. Dimitri Basov's group on near-field imaging of surface polariton in two-dimensional materials. This technique provides a …

Investigation of exciton dynamics and electronic band structure of InP and GaAs nanowires
… effects were observed by increasing the carrier densities using pulsed laser excitation.</p><p> Further, polarized TRPL spectroscopy was used to study exciton dynamics in these nanowires at 10K. The polarization of the emitted PL was monitored at the exciton emission peak (1.515~eV) as a …

Analysis of coulomb interaction using modified particle-particle-particle-mesh method in Monte Carlo simulation
… (EMC) simulator, MOCA3D, to treat the Coulomb scattering, i.e. carrier-carrier and carrier-impurity scattering. We show that most of the problems in the particle{mesh (PM) based scattering rate approach are solved by the P3M method. The properties of the Coulomb scattering are analyzed by …
