Title: Evaluation of crystalline quality of traveling heater method (THM) grown Cd0.9Zn0.1Te0.98Se0.02 crystals

Abstract

Because of its excellent opto-electronic properties, CdZnTe (CZT) has been the material of choice for x- and gamma-ray detectors operable at room temperature. CZT is the leading commercially available room-temperature radiation detector material today. Although much progress has been made over the past three decades, today's CZT crystals still face certain challenges, especially the presence of the performance-limiting materials defects and the associated relatively high production cost. In this regard, CdxZn1−xTeySe1−y (CZTS) is emerging as a next-generation compound semiconductor, which overcomes some of the limitations of CZT technology for the stated applications. Here, we conducted a study to evaluate the crystalline quality of the traveling heater method grown CZTS with an optimized alloy composition, i.e., Cd0.9Zn0.1Te0.98Se0.02. The as-grown samples were evaluated by low-temperature photoluminescence (PL) spectroscopy and high-resolution x-ray diffraction using the synchrotron light source at Brookhaven National Laboratory. The full width at half maximum of both the PL and x-ray rocking curves was observed to be broadened due to the lattice disorder of the quaternary compound, eventually degrading the crystalline quality. This was consistent with density functional theory calculations.

Performance Study of Virtual Frisch Grid CdZnTeSe Detectors

Journal Article Roy, Utpal N. ; Camarda, Giuseppe S. ; Cui, Yonggang ; ... - Instruments

Nuclear detectors for x-ray and gamma-ray spectroscopy and imaging are a vital tool in many homeland security, medical imaging, astrophysics and other applications. Most of these applications require room-temperature operation due to the operational constraints imposed by a cryogenic cooling system. CdZnTe (CZT) has been the main material with the desired detection properties, and CZT crystals have been used commercially for three decades. However, CdZnTe still suffers from long-standing issues of high densities of performance-limiting intrinsic defects such as Te inclusions and networks of dislocation walls (sub-grain boundaries).

Role of Selenium Addition to CdZnTe Matrix for Room-Temperature Radiation Detector Applications

Journal Article Roy, Utpal N. ; Camarda, G. S. ; Cui, Y. ; ... - Scientific Reports

Because of its ideal band gap, high density and high electron mobility-lifetime product, cadmium zinc telluride (CdZnTe or CZT) is currently the best room-temperature compound-semiconductor X- and gamma-ray detector material. However, because of its innate poor thermo-physical properties and above unity segregation coefficient for Zn, the wide spread deployment of this material in large-volume CZT detectors is still limited by the high production cost. The underlying reason for the low yield of high-quality material is that CZT suffers from three major detrimental defects: compositional inhomogeneity, high concentrations of dislocation walls/sub-grain boundary networks and high concentrations of Te inclusions/precipitates.

A Comparison of Point Defects in Cd_1-xZn_xTe_1-ySe_y Crystals Grown by Bridgman and Traveling Heater Methods

Journal Article Gul, R. ; Roy, U. N. ; Camarda, G. S. ; ... - Journal of Applied Physics

In this paper, the properties of point defects in Cd1-xZnxTe1-ySey (CZTS) radiation detectors are characterized using deep-level transient spectroscopy and compared between materials grown using two different methods, the Bridgman method and the traveling heater method. The nature of the traps was analyzed in terms of their capture cross-sections and trap concentrations, as well as their effects on the measured charge-carrier trapping and de-trapping times, and then compared for the two growth techniques. The results revealed that Se addition to CdZnTe can reduce the VCd- concentration. In Travelling Heater Method (THM) and Bridgman Method (BM) grown CZTS detectors, besides amore »« less

Microhardness Study of CdZnTeSe Crystals for X-ray and Gamma ray Detectors

Conference Moravec, P. ; Roy, Utpal

A quaternary material Cd_1-x ZnxTe_1-y Sey (CZTS) is currently under investigation for its application as a material for hard X-ray and gamma ray detectors. The addition of selenium was found to be very effective in suppressing the formation of sub-grain boundaries and their networks. The CZTS crystals were grown by the THM technique at Brookhaven National Laboratory. The ingots are ~52 mm in diameter, weighting about 1.0-1.2 kg. In general, the ingots were crack-free except near the Te-CZTS interface. The goal of the presented work is to increase our understanding of key factors influencing the crystal quality and its suitabilitymore »« less

Growth interface study of CdTeSe crystals grown by the THM technique

Journal Article Roy, Utpal N. ; Camarda, Giuseppe S. ; Cui, Yonggang ; ... - Journal of Crystal Growth

The Traveling Heater Method (THM) is a widely accepted technique to grow high-quality detector grade CdTe and CdZnTe ingots, especially for X-ray and gamma-ray detector applications. Unlike melt-growth techniques, the growth interface for ingots produced by the THM technique consists of two different compounds, viz. the solidified region (just below the interface) consists of the compound to be grown (e.g., CdZnTe for CdZnTe growth), while the molten zone just above the growth interface consists of Te-rich CdZnTe. Thus, optimization of the growth parameters is critical to obtain a clean growth interface with the required shape and presence of minimal Te-richmore »« less
