Recent theoretical results on magnetotransport of electrons in a 2D system in the range of moderately strong transverse magnetic fields are reviewed. The phenomena discussed include: quasiclassical memory effects in systems with various types of disorder, transport in lateral superlattices, interaction-induced quantum magnetoresistance, quantum magnetooscillations in dc and ac transport, and os...

We propose a first principles method of calculating the photo-component of tunneling conductivity of a specific superlattice (SL) photovoltaic structure: an InP/InGaAs P-I(SL)-N solar cell. The method we follow is based on the generalized Greenwood-Kubo formulation and on the causal form of the Green’s function. The vertical conductivity (along the growth direction of the device), under illumin...

Exploring the thickness-dependent electronic properties of ultrathin transition metal dichalcogenides is crucial for novel optoelectronic devices. Particularly important experimental information regarding bandgap width. This scarce and often inconsistent among several measurement techniques that were employed this task, such as optical absorption, scanning tunneling spectroscopy, photoconductiv...

At room temperature, the FIB fabricated tungsten meander wire shows positive photoconductivity features through generation of extra charge carriers by absorbing photons required energy from illuminated 532 nm wavelength laser light.
