Defect induced Raman active modes in Mn doped ZnO thin films
Autor: M. K. Jayaraj, Arun Aravind, K. Hasna
Publikováno v: SPIE Proceedings.
Zinc oxide is a II-VI semiconductor with a wide direct band gap of about 3.37 eV at room temperature. Among the various growth techniques of 'Mn' doped ZnO thin films, pulsed laser deposition (PLD) offers the advantages such as deposition at relative
