In this paper, ZnO nanomaterials with high effective specific surface area have been prepared and subsequently deposited on the SAW transducer as sensitive layer, finally the responses of the sensor to different ethanol gas concentrations were investigated at room temperature.
The spectral photoresponse characteristics for visible blind GaN/AlGaN p-i-n photodiode have been numerically studied. Effects of the absorption layer thickness and the n-layer thickness on the photoresponse spectra have been investigated. Our work shows that the absorption layer thickness and n-layer thickness have important impact on the peak value of photoresponse spectra and rejection ratio of...
In this paper, we report on two-dimensional (2D) numerical simulations of photoresponse for HgCdTe infrared photodiode. Effects of conduction band non-parabolic and band gap narrowing (BGN) have been investigated in detail. By taking into account the contributions: (i) the Burstein-Moss (BM) shift with a non-parabolic conduction band, (ii) the BGN effect, and (iii) the Hg-vacancy-induced acceptor...
