Description
The I-V characteristic of amorphous As4Se4Te2 was studied at relatively low temperature ranging from -158deg C to -67deg C. Three distinct regions of current-voltage range were observed and discussed on the basis of space-charge limited-current mechanism. A number of conduction parameters were calculated for fresh and γ-radiation samples. The effect of γ-radiation and thermal annealing process on the conduction behaviour of the test sample and on the conduction parameters were also discussed. (orig.)
Abstract (German)
Die Strom-Spannungs-Charakteristik von amorphem As4Se4Te2 wurde bei relativ niedrigen Temperaturen im Bereich von -158deg C ... -67deg C untersucht. Drei voneinander verschiedene Bereiche im Strom-Spannungs-Verlauf konnten beobachtet werden und sind auf der Grundlage des begrenzten Raumspannungsstrom-Mechanismus diskutiert worden. Eine Anzahl von Leitfaehigkeitsparametern wurde fuer frische und γ-bestrahlte Proben berechnet. Der Effekt der γ-Strahlung und des thermischen Ausheilvorgangs auf das Leitfaehigkeitsverhalten der Testproben und auf die Leitfaehigkeitsparameter wurden ebenfalls besprochen.
