摘要
In this paper, we present an automatized system for simultaneous measurement of conductivity sigma and thermoelectric power S: measurements are allowed for temperatures ranging from 130 K to 360 K on brittle semiconductor layers. As an example of the application, results obtained in the case of polymer (PPP) layers implanted with Na ions are presented: with high energy implantation (E = 250 keV) we observe only a defect semiconduction of p type while at low energy (30 keV) an electronic n type conduction appears.
