Abstract

The changes in the optical transparency of PbTe monolayers induced by post-evaporation heat treatment are described. The monolayers are typically a few microns in thickness and heat treatment reduces the carrier density from about 10¹⁸ (n-type) per cm³ to 10¹⁷ per cm³ : the source material is 10¹⁹ (ptype) per cm³. The process seems to involve the diffusion of O₂ at a reaction rate equivalent to an energy of 0.83 eV.
