Effect of ACRT Technology on the Large Size ZnTe Crystals Grown by Solution Method and Corresponding Terahertz Properties

Abstract

Terahertz (THz) technology has immersing potential applications in industrial non-destructive testing, scientific research and military engineering. However, as the most commonly used THz emission and detection electro-optical material, the ZnTe single crystal growth still faces great challenges. In order to achieve ZnTe single crystals with large size, good homogeneity and high performance, an accelerated crucible rotation technique (ACRT) was introduced in growing ZnTe crystals by temperature gradient solution growth method (TGSG). Intrinsic ZnTe single crystals with high crystalline quality were successfully prepared. Through the simulation of flow field and solute 第 3 期

Role of Pyramidal Low-Dimensional Semiconductors in Advancing the Field of Optoelectronics

“…Similarly, the preparation of GaN NRs under liquid-phase conditions is challenging, often leading to their fabrication via vapor-phase deposition [149]. In contrast to the more stringent growth conditions required for GaN, the preparation of ZnTe can be achieved using both the gas-and liquid-phase approaches, although the morphology of nanoscale ZnTe prepared via the liquid-phase route is difficult to control [162,163]. Accordingly, controlling the reaction conditions using the MBE method remains the most effective method for regulating the growth morphologies of pyramidal ZnTe NRs [148].…”
