Title: X-ray photoemission analysis of chemically modified TlBr surfaces for improved radiation detectors

Abstract

We subjected device-grade TlBr to various chemical treatments used in room temperature radiation detector fabrication to determine the resulting surface composition and electronic structure. As-polished TlBr was treated separately with HCl, SOCl₂, Br:MeOH and HF solutions. High-resolution photoemission measurements on the valence band electronic structure and Tl 4f, Br 3d, Cl 2p and S 2p core lines were used to evaluate surface chemistry and shallow heterojunction formation. Surface chemistry and valence band electronic structure were correlated with the goal of optimizing the long-term stability and radiation response.

Thallium bromide (TlBr) crystals subjected to hydrochloric acid (HCl) chemical treatments have been shown to advantageously affect device performance and longevity in TlBr-based room temperature radiation detectors, yet the exact mechanisms of the improvements remain poorly understood. Here in this paper, we investigate the influence of several HCl chemical treatments on device-grade TlBr and describe the changes in the composition and electronic structure of the surface. Composition analysis and depth profiles obtained from secondary ion mass spectrometry (SIMS) identify the extent to which each HCl etch condition affects the detector surface region and forms of a graded TlBr/TlBr_1-xCL_x surface heterojunction.more »« less

Device-grade thin-film CuInSe{sub 2} was subjected to various chemical treatments commonly used in photovoltaic device fabrication to determine the resulting microscopic surface composition/morphology and the effect on II-VI/CuInSe{sub 2} heterojunction formation. HCl (38%), Br-MeOH (<1% Br), (NH{sub 4}){sub 2}S, and NH{sub 4}OH/thiourea solutions were used separately to modify the surface chemistry of the CuInSe{sub 2} polycrystalline films. Scanning electron microscopy was used to evaluate the resultant surface morphology. Angle-resolved high-resolution photoemission measurements on the valence band electronic structure and Cu 2p, In 3d, Ga 2p and Se 3d core lines were used to evaluate the chemistry of the chemically treatedmore »« less

Surface passivation of device-grade radiation detector materials was investigated using x-ray photoelectron spectroscopy in combination with transport property measurements before and after various chemical treatments. Specifically Br-MeOH (2% Br), KOH with NH{sub 4}F/H{sub 2}O{sub 2} and NH{sub 4}OH solutions were used to etch, reduce and oxidize the surface of Cd{sub (1-x)}Zn{sub x}Te semiconductor crystals.

Analysis of the electronic structure of Hf(Si{sub 0.5}As{sub 0.5})As by X-ray photoelectron and photoemission spectroscopy

Journal Article Grosvenor, Andrew P. ; Cavell, Ronald G ; Mar, Arthur ; ... - Journal of Solid State Chemistry

The ternary hafnium silicon arsenide, Hf(Si{sub x}As{sub 1-x})As, has been synthesized with a phase width of 0.5{<=}x{<=}0.7. Single-crystal X-ray diffraction studies on Hf(Si{sub 0.5}As{sub 0.5})As showed that it adopts the ZrSiS-type structure (Pearson symbol tP6, space group P4/nmm, Z=2, a=3.6410(5) A, c=8.155(1) A). Physical property measurements indicated that it is metallic and Pauli paramagnetic. The electronic structure of Hf(Si{sub 0.5}As{sub 0.5})As was investigated by examining plate-shaped crystals with laboratory-based X-ray photoelectron spectroscopy (XPS) and synchrotron radiation photoemission spectroscopy (PES). The Si 2p and As 3d XPS binding energies were consistent with assignments of anionic Si{sup 1-} and As{sup 1-}. However,more »« less
