- Abstract
- Zn1.10CoxMn1.90-xO4 (0 <= x <= 0.25) specimens were prepared using a conventional solid state reaction method. We investigated the structural and electrical properties with varying amounts of Co for application in IR detectors. All specimens exhibited a very dense microstructure and the average grain size decreased slightly with an increase in the composition ratio of Co ions. The Zn1.10Co0.05Mn1.85O4 specimen shows the highest B-value of 5025 K, and the Zn1.10Co0.25Mn1.65O4 specimen shows the minimum resistivity of 100 k Omega center dot cm. The responsivity, s noise voltage and detectivity of the Zn1.10Co0.10Mn1.80O4 specimen are 0.03 V/W, 6.36 x 10(-5)V and 2.010(4) cmHz(1/2)/W, respectively.
