Abstract

We have grown single crystals of solid solutions based on the layered compound semiconductor TlGaS2 containing up to 2 mol % praseodymium and characterized them by X-ray diffraction. The optical absorption edge of the TlGaS2〈Pr〉 solid solutions has been studied in the temperature range 100–200 K, and the edge exciton peak position has been determined as a function of temperature for all of the TlGaS2〈Pr〉 compositions studied.

镨掺杂对TlGaS2化合物晶体结构和光学吸收边的影响
我们以含有高达2mol %镨的层状化合物半导体TlGaS2为基础,生长出固溶体的单晶,并用x射线衍射对其进行了表征。研究了TlGaS2 < Pr >固溶体在100-200 K温度范围内的光学吸收边缘,并确定了所有TlGaS2 < Pr >组成物的边缘激子峰位置与温度的关系。

期刊介绍: Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
