Hydrogen fuel cells have been designed and fabricated with an aim to investigate effect of cell clamping pressure and hydrogen flowrates on the performance of fuel cells. Fuel cells with active area 1.9 cm × 1.6 cm were fabricated with aluminum anod

In this paper, we study the structure of the solid selenium (Se) formed by the vapor deposition method. We provide direct visual evidence that faceted crystal-like shapes obtained from vapor phase deposition are a self-assembly of linear strands that

We report a comprehensive study of the growth of GaN layers on (1 0 0)-oriented Ga2O3 substrates by metalorganic vapour phase epitaxy (MOVPE), especially the improvement on using an intermediate facet-control layer between the low-temperature buffer

Bulk gallium phosphide (GaP) crystallizes in the zinc-blende (ZB) structure and has an indirect bandgap. However, GaP nanowires (NWs) can be synthesized in the wurtzite (WZ) phase as well. The contradictory theoretical predictions and experimental re

The high light-output efficiencies of In(x)Ga(1-x)N quantum-well (QW)-based light-emitting diodes (LEDs) even in presence of a large number of non-radiative recombination centers (such as dislocations) has been explained by localization of carriers i

The microstructure of epitaxial InN layers has been analyzed by high-resolution X-ray diffraction. Various mosaic block parameters like the tilt and twist between the blocks and an estimate of their lateral coherence lengths have been obtained for a

We report polarization-sensitive solar-blind metal-semiconductor-metal UV photodetectors based on (11-20) a-plane AlGaN. The epilayer shows anisotropic optical properties confirmed by polarization-resolved transmission and photocurrent measurements,

We measure the thermal conductivity ($\kappa$) of individual InAs nanowires (NWs), and find that it is 3 orders of magnitude smaller than the bulk value in the temperature range of 10 to 50 K. We argue that the low $\kappa$ arises from the strong loc

We study the emission mechanisms of THz radiation from InAs nanowires (NWs) using femtosecond infrared (IR) pump beam and THz probe in a time-resolved reflection geometry setup at room temperature. We compare the spectra of InAs NWs with that of a p-

We present our investigation of the THz radiation emission from InAs nanowires (NW) grown on a GaAs substrate. We also compare the emitted power of the radiation from InAs nanowires with a p-InAs crystal, a standard THz emitter. The absolute emitted
