Abstract
Gold contacts electrolessly deposited on (CdZn)Te surface from methanol and water-based solutions were studied. We have observed strong injection at voltages higher than 100 V that disappeared when using contacts on lateral sides instead of bottom ones.
In our opinion this phenomenon depends on crystallographic orientation of contact surfaces. After additional surface treatment and applying guard ring we have obtained sample with bulk specific resistivity of 1E12 Ωcm.
Alcohol-based contacts showed better mechanical (adhesion and uniformity) and very similar electrical (I-V curves) properties in compliance with water-based ones.
