Abstract

M-Cu(Zn,Cd)$InS_2$-M compound semiconductors in planar form prepared by the spray pyrolysis method. Frequency $(omega)$ dependent conductivity $(sigma)$ of the films have been investigated and observed that at reasonably higher frequencies the conductivity varied as $omega^s$ with s ranging from 0.8 to 1. In one of the specimen, the conductivity observed to vary with s=1.45 which is believed to be due to the lossy mechanism taking place. On the other hand s being less than 1 indicates that the conduction process is the hopping process.

Özet

M-Cu(Zn,Cd)$InS_2$-M bileşik yarıiletkenler planar formda "spray pyrolysis" yöntemiyle elde edilmiştir. Film iletkenliğinin $(omega)$ frekansa $(sigma)$ bağımlılığı incelenmiştir. Yüksek frekanslarda iletkenliğin $omega^s$ ile değiştiği ve s'nin 0.8 ile l arasında değerler aldığı gözlenmiştir. Numunenin birinde, iletkenlik s=1.45 ile değişmektedir. Bunun kayıp mekanizması nedeniyle olduğuna inanılmaktadır. Diğer taraftan, s'nin l'den küçük olması iletimin hopping olayından kaynaklandığını göstermektedir.
