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...

Copper and iron chalcogenides for efficient solar absorption

Creator:

Platt, Heather A. S.

Abstract:

This dissertation outlines two approaches for improving the efficiency and reducing the cost of photovoltaic energy generation. First, the structures of known binary copper and iron compounds are used to choose the promising compositions Fe₂XS₄ (X = Si, Ge), Cu₃TaQ₄ (Q = Se, Te), and BaCuQ'F (Q' = S, Se,...
