Band alignment at the BaCuSeF/ZnTe interface

Creator:

Zakutayev, Andriy, Tate, Janet, Platt, Heather A. S., Keszler, Douglas A., Barati, Alireza, Klein, Andreas, and Jaegermann, Wolfram

Abstract:

In situ photoemission spectroscopy experiments are used to characterize the interface between ZnTe and the wide band gap p-type semiconductor BaCuSeF. The contact is characterized by a null valence-band offset, a large conduction-band offset, and a chemically graded interface. By applying the transitivity rule for band offset and on the...

Electronic properties of BaCuChF (Ch = S,Se,Te) surfaces and BaCuSeF/ZnPc interfaces

Creator:

Zakutayev, Andriy, Tate, Janet, Platt, Heather A. S., Keszler, Douglas A., Hein, Corinna, Mayer, Thomas, Klein, Andreas, and Jaegermann, Wolfram

Abstract:

BaCuChF (Ch=S,Se,Te) surfaces and BaCuSeF interfaces with zinc phthalocyanine (ZnPc) were studied by photoelectron spectroscopy. BaCuChF compounds oxidize when exposed to ambient atmosphere. Se capping layers were studied as a means to produce representative surfaces for photoelectron spectroscopic measurements. Decapped BaCuSeF surfaces remain O-free and C-free when the Se layer...
