Simulation of p-GaN/i-InαGa(1-α)N/n-GaN Solar Cell for Maximum Efficiency
The external efficiency of nonpolar p-GaN/i-In α Ga(1-α)N/n-GaN solar cells was simulated using limited constituent approach. Reduction of the poor effect of conduction band peak is done...

H2O on Io? IR spectra of SO2/H2O mixed ices in the 5000-450 cm−1 region
Laboratory transmission IR spectra of relatively thick films (up to ∼500 μm) of mixed H2O and SO2 ices were measured at several temperatures between 10 and 130 K in the range 5000-450 cm−1. In addition to the str...

On PAHs as Interstellar Grains: Infrared Absorption Coefficients
There are several inconsistencies with the interesting proposal that PAHs are the source of infrared continuum and emission features and the visible diffuse bands. We report absolute infrared cross-sections fo...

Certain phenological characters of the shrub layer of Kumaun Himalayan forests
The phenology of 49 shrub species in five forest types occurring along an altitudinal gradient (350–2150 m) in Kumaun Himalaya has been studied. The evergreen leaf-exchanging taxa accounted for nearly half of ...
