Solar Energy Materials and Solar Cells. 170:27-32
We report on a high-performance intermediate band solar cell (IBSC) based on Cr-doped ZnTe (ZnTe:Cr) fabricated using a pulsed laser deposition (PLD) method. Chromium (Cr) was uniformly distributed in the ZnTe:Cr thin film with an atomic concentratio

We report a new approach to the synthesis of molybdenum disulfide (MoS 2 ) quantum dots (QDs) that uses a single layer MoS 2 grown by chemical vapor deposition (CVD) method as a precursor. The MoS 2 QDs were formed by a thermal annealing process at 5

Two-dimensional (2D) crystals have a multitude of forms, including semi-metals, semiconductors, and insulators, which are ideal for assembling isolated 2D atomic materials to create van der Waals (vdW) heterostructures. Recently, artificially-stacked

Pressure-sensitive electronic skin composed of a hierarchical structural array exhibits outstanding linear and high sensitivity in the pressure range exerted by gentle touch. By virtue of monolayer graphene acting as electrode material, this device c

We have studied a successive two-step chemical vapor deposition (CVD) method to prepare large-scale MoS2 thin films using a horizontal hot wall furnace. The CVD growth was followed by evaporation of the MoO3 precursor on ~ 2.5 × 2.5 cm2 SiO2/Si subs

We studied oxygen incorporation into ZnTe thin films with nitrogen and oxygen plasma during a plasma-assisted pulsed laser deposition (PA-PLD). It was shown that ZnTe:O layer formed with oxygen plasma exhibits an enhancement of optical transparency i

An undoped a -plane GaN epi-layer was grown on r -plane sapphire substrate with silica nano-spheres by metal organic chemical vapor deposition. Defect states in the GaN epi-layer with Pt Schottky diode and Ti/Au Ohmic contact were characterized by us
