Low Frequency Noise of the CdTe Crystals

Original language description

Experimental studies of transport and noise characteristics of CdTe bulk single crystals have been carried out. The noise measurement was used to characterized the quality of sample surface and contact technology. As a quality indicator we have choose the 1/f noise. In this case the 1/f noise is generated in sample volume, on surface and contacts. The main problem to be solved was the separation of these noise sources. The noise spectral density was measured by four probe method to separate contact noisse from the other sources. To distinguish between 1/f noise generated in sample volume and on the surface the noise measurement was performed as a function of incident light wavelengths for constant electric field and current was varied both by the sample illumination and photon energy change. There are three different 1/f noise sources: (i)bulk 1/f noise generated by sub band gap energy photons with current noise spectral density proportional to first power of current, (ii)surface 1/f n

Nízkofrekvenční šum v krystalech CdTe

Czech description

Článek pojednává o experimentálním studiu transportu a šumových charakteristik v objemu krastalů CdTe. Šumové charakteristiky jsou mírou kvality povrchu vzorků a jejich kontaktů. Jako indikátor spolehlivosti jsme vybrali 1/f šum, který vzniká v objemu ana kontaktech. Hlavní problém je ve zjišťování příspěvku těchto zdrojů do celké úrovně 1/f šumu.
