Dual-band electrochromic devices capable of the spectral-selective modulation of visible (VIS) light and near-infrared (NIR) can notably reduce the energy consumption of buildings and improve the ...

He insists that this question must be tackled by examining real and not ideal crystals Radiotekhnika i Elektronika”, No. 12, Dec., 1960). Bonch-Bruyevich points out that in strongly alloyed junctions, ...

This paper reports on an all-oxide thin film piezotronic P-N heterojunction diode incorporating vertically-stacked structure of N+-ITO/P-type nickel oxide/N-type zinc oxide as a flexible energy ...

At low voltages, the bands are close enough for efficient tunneling. As voltage increases, these things happen: Band misalignment: The applied voltage pushes the energy bands further apart, reducing ...

Among the latter were a stabilised front end amplifier for a Band II receiver, a type of synchrodyne receiver and an age system for control tunnel diodes. “But,”said Mr. Alexander,,one of the ...

Figures 2C,F show the band structure for ZnO B i -B Zn and B i -N O ZnO, respectively. Compared with the band gap of pure ZnO (0.74 eV), the band gap for B i -B Zn ZnO is 0.14 eV. The band gap for B i ...

There are many factors behind this low conversion efficiency for laser diodes. Quite a few relate to the high activation energy of the magnesium acceptor in p-type, magnesium-doped layers of GaN and ...
