Originální abstrakt

This paper presents the results of experimental studies of transport and noise characteristics of CdTe single crystals. Though no universal mechanism has been identified for flicker noise or 1/f noise, it is the most ubiquitous form of noise in nature. Phenomena that have no obvious connection like heartbeat, cell membrane potential, financial data, DNA sequences and transistors exhibit fluctuations with a 1/f character. As the term "1/f" suggests, a spectral density that increases without limit as frequency decreases, characterizes this kind of noise. Flicker noise in the CdTe single crystals was studied. Two CdTe detectors were used; both have p-type conductivity. One of them has low-ohmic contacts (F33B8), another one have high-ohmic contact (452D).
