中文摘要: 随着第三代半导体技术的发展,碲锌镉(Cd1-xZnxTe,0≤x≤1,简称CZT)晶体作为一种高效的半导体材料,已成功应用于多种探测器。该类探测器采用创新的一步转换技术,直接将高能射线转化为电荷信号,实现对射线能量、位置及时间的精准测量,可有效解决目前采矿业面临的高品位矿石减少、低品位矿石难选,以及分选设备响应慢、能耗高、噪声大等问题。本文综述了国内外CZT晶体的研究现状,对比了各类生长工艺的优缺点。同时,深入评估了CZT晶体组分均匀性控制、固-液界面控制以及晶体中缺陷控制与消除等技术。在此基础上,展望了CZT晶体的应用前景及发展趋势。

Abstract:Depletion of high-grade ore deposits, coupled with growing difficulty of separating low-grade ores, has exposed critical shortcomings in current ore separation technologies: sluggish response, high energy consumption, and elevated noise at room temperature. The advent of third-generation semiconductors has positioned Cd1-xZnxTe (0≤x≤1, abbreviated as CZT) as a highly efficient detector material. Leveraging an innovative single-step conversion mechanism, Cd1-xZnxTe (0≤x≤1) detectors directly transduce high-energy radiation into charge signals, enabling precise determination of energy, position and time. This paper provided a comprehensive survey of worldwide research on Cd1-xZnxTe (0≤x≤1) crystals, systematically comparing the merits and drawbacks of various growth techniques. Detailed assessments were presented on controlling compositional uniformity, managing the solid-liquid interface, and eliminating—or at least mitigating—bulk and surface defects. Building on these analyses, the outlook for future applications and development trajectories of Cd1-xZnxTe (0≤x≤1) crystals was discussed.
