An analytical least squares method for precise determination of the lattice constant for cubic crystals using a standard reference material as an external standard 2θ-calibrant was used in this investigation. The best estimated value of the lattice constant (a) for CdTe0.9Se0.1 was determined to be 6.441 (2) Å at 298 K. This value gradually increased to 6.457 (2) Å at 773 K. A similar trend was observed in the unit cell volume, which increased from 267.2(2) Å3 to 269.3(2) Å3 as the temperature changed from RT to 773 K. The thermal expansion coefficient was found to be 3.91 × 10-6 K-1 at 298K and continuously increased to 9.73 × 10-6 K-1 at 773 K.  ISSN : 0925-8388  Journal Name : Journal of Alloys and Compounds  Volume : 387  Issue Number : 1  Publishing Year : 1426 AH 2005 AD  Article Type : Article  Added Date : Sunday, January 1, 2012  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email صالح هديهد الحنيطي Al-Heniti, Saleh H Researcher Doctorate salheniti@kau.edu.sa Ali Al-Hajry Al-Hajry, Ali Researcher Doctorate   Files File Name Type Description  31911.pdf pdf Abstract Back To Researches Page
