Infrared spectroscopy of dilute magnetic semiconductors

Perex

This talk will present recent work on two alternative families of dilute magnetic semiconductor materials. The first half of the talk will present the study of undoped and Cr and V-doped Sb2Te3 crystals, showing classical Drude conductivity behavior. The second half of the talk will review the recent attempts to prepare Ge:Mn by ion implantation. Structural, magnetic and temperature dependent infrared characterizations will be discussed.
