Transport properties of vertical heterostructures under light irradiation

Vertical Electron Transport in GaN/AlGaN Heterostructures

Nonequilibrium dc and large-signal ac vertical electron transport in GaN/AlGaN heterostructures is investigated by Monte Carlo simulations. The symmetric two-barrier GaN/AlGaN heterostructures are studied. The results of simulations show that polarization charges have a profound effect on dc and large-signal ac characteristics of vertical electron transport in GaN/AlGaN heterostructures. Under ...

Transport properties of graphene nanoribbon heterostructures

We study the electronic and transport properties of heterostructures formed by armchair graphene nanoribbons with intersections of finite length. We describe the system by a tight-binding model and calculate the density of states and the conductance within the Green’s function formalism based on real-space renormalization techniques. We show the apparition of interface states and bound states i...

Enhancing Photocatalytic Activity of Nitrogen Doped TiO2 for Degradation of 4-Chlorophenol under Solar Light Irradiation

The nitrogen doped TiO2 as heterogeneous photocatalyst via sol-gel method were successfully synthesized. The physicochemical, morphological and textural characteristics of the obtained TiO2 samples were characterized by advanced analysis techniques. The photocatalytic activity of the samples were evaluated for degradation of 4-CP under solar irradiation. The as-synthesized photocatalysts were c...
