Electrically induced spectral and spatial instabilities of photoresponse CdZnTe crystals
The features of I = f(λ) and I = f(x) dependences in Cd₁-ₓZnₓТе crystals containing a variety of two-dimensional structural defects, which become manifested under simultaneous action of biasing and modulating fields, have been exposed and explored. Basing on comparison of spectral and coordinate...

Выявлены и исследованы особенности зависимостей I = f(λ) и I = f(x) кристаллов Cd₁-ₓZnₓТе, содержащих двумерные дефекты структуры, которые проявляются при одновременном воздействии смещающего и модулирующего полей. На основе сопоставления спектральных и координатных зависимостей фототока и их вейвлет-спектрограмм, полученных при соответствующих полярности, частоте и скважности модулирующего П-образного напряжения, установлена связь между определенными диапазонами длин волн спектральной неустойчивости и координатами порождающих их ансамблей дефектов структуры.

The features of I = f(λ) and I = f(x) dependences in Cd₁-ₓZnₓТе crystals containing a variety of two-dimensional structural defects, which become manifested under simultaneous action of biasing and modulating fields, have been exposed and explored. Basing on comparison of spectral and coordinate photocurrent dependences and their wavelet-spectrograms obtained at appropriate polarity, frequency, and on-off time ratio characteristics of the modulating square pulse voltage, an relation has been found between certain wavelength ranges of spectral instability and coordinates of structural defects aggregates originating those waves. |
