2014 Cet article traite des émissions de paires donneurs-accepteurs (D.A.P.) dans le ZnSe cubique et des émissions bande de conduction-accepteurs (BC-A) qui leur sont corrélées. Les mesures directes des positions des maximums des bandes d'émission sous excitation ne sont pas assez précises pour permettre de faire un choix entre les différents donneurs et accepteurs possibles. Nous faisons d'abord un ajustement avec la théorie de Eagles pour les bandes BC-A ; puis un programme de calcul des profils d'émission D.A.P. conduit à la valeur de l'énergie coulombienne d'interaction et permet d'obtenir l'énergie d'ionisation des donneurs. Des expériences de thermoluminescence donnent des profondeurs de pièges corrélées aux accepteurs observés ainsi qu'à des pièges plus profonds. Pour finir on discute les conditions d'observation des différentes bandes d'émission. Abstract. 2014 This paper is concerned with the donor-acceptor pair emission (D.A.P.) in cubic ZnSe and the correlated conduction band-acceptor emission (BC-A). Direct measurements of the peak positions of the bands are not accurate enough to enable a choice to be made between the different possible donors and acceptors. We first made the BC-A shape with Eagles' theory obtaining the ionization energies of the acceptors ; then a computer calculation of the D.A.P. emission profile leads to the coulombic energy correction and allows the donor ionization energies to be obtained. Thermoluminescence experiments give trap depths correlated with the observed acceptors, and also deeper traps. A discussion is given of the experimental situation leading to the observation of the different emission bands.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
