Summary
In this paper we discuss the chemisorption forms of oxygen (O −2 and O−) and the energy levels (0.75 and 1.2 eV) of the oxygen centres of the oxygen chemisorption on the surface of CdSe thin films. It was found that the nonstoichiometric Cd atoms are the chemisorption centres of oxygen in the molecular form and the selenium vacancies are those of oxygen in atomic form.
Riassunto
Si discutono le forme di chemiadsorbimento di ossigeno (O2 − e O−) e anche le posizioni energetiche dei centri di ossigeno (0.75 c 1.2 eV) sulla superficie di strati sottili di CdSe. È stato determinato che gli atomi non stoichiometriei del cadmio servono come centri per l'assorbimento delle molecole di ossigeno e che gli atomi di ossigeno si chemiadsorbono alle vacanze di selenio.
