Growth of Undoped GaAs Single Crystal by Pulling-Down Method

Abstract:

Undoped GaAs single crystal has been grown in PBN crucibles by the pulling-down method. The temperature profile of the furnace was optimized with a narrow melting zone and a small temperature gradient at the solid-liquid interface. Quartz ampoules were used to protect the evaporation of As during the growth and the deformation of the ampoule was discussed as a function of temperature, time and pressure differential. A Ø56 mm×70 mm GaAs crystal with nearly 100 % single crystalline yield was obtained. X-ray rocking curve analysis revealed the excellent crystalline quality. The average EPD and electrical properties of the crystal were tested comparable to those of the crystal produced by the VGF method. Therefore, the pulling down method was a feasible approach for GaAs crystal production.

Structure Characterizations and Growth of Bulk ZnSe Single Crystals by Zn(NH₄)₃Cl₅ Transport

Authors: Huan Yong Li, Ke Wei Xu, Wan Qi Jie

Abstract: Two chemical vapor transport methods with Zn(NH4)3Cl5 transport agent were developed to grow ZnSe bulk single crystals. Two kinds of Zn-rich ZnSe single crystals, conical crystal and flake crystal，were grown directly from untreated ZnSe polycrystals and two elements, respectively. The structure characters, purity and etch pit density were studied by rotating orientation XRD, PL spectrum and optical microscope. The contrastive investigation between two growth results indicated that the conical crystal was composed of (111) and (100) faces, and the flake crystal exhibited only (111) face. Moreover, the vicinal interface leaning to (111) face by the angle of 3.1° was the dominative growth face in vapor growth system, and growth occurs by layer-by-layer model. FWHM of RO-XRD pattern of ZnSe (111) face was 24sec for conical ZnSe crystal and 48s for ZnSe flake crystal. The results suggested that high-quality ZnSe crystals can be grown from the chemical vapor transport method with Zn(NH4)3Cl5 transport agent.

Polycrystal Synthesis and Single Crystal Growth of PbI₂

Authors: Xin Zhao, Ying Rong Jin, Xing Hua Zhu

Abstract: High-pure and single-phase PbI2 polycrystal was synthesized by Pb and I elements (99.9999%) according to the stoichiometry of PbI2 with excess of 0.3% Pb through modified two-zone vapor-transporting method (MTVM). The synthesis reaction was carried in a special quartz ampoule to prevent the ampoule exploding by controlling the temperature. With presynthesized polycrystal, an integral PbI2 single crystal with 15 mm in diameter and 25 mm in length was grown by vertical Bridgman method (VBM). The as-grown crystal was characterized by X-ray diffraction (XRD), ZC36 megger and Infrared (IR) spectrophotometers. XRD analysis indicated the structure of PbI2 crystal is 2H with hexagonal space group of , the lattice constants of a and c are 0.4560 nm and 0.6979 nm, respectively. The IR transmittance of a sample of 2.5 mm thickness is about 40% in the range from 4000 to 400 cm-1. Resistivity of the crystal is about 1013 Ωcm magnitude. These results demonstrate that the quality of the as-grown crystal is high enough for applications of room temperature nuclear radiation detectors.

Growth of ZnGeP₂ Single Crystal by Three-Temperature-Zone Furnace

Authors: Xin Zhao, Shi Fu Zhu, Yong Qiang Sun

Abstract: In order to meet the requirements of growing high-quality ZnGeP2, a crystal growth furnace with three-temperature-zone was designed and fabricated based on a conventional vertical two-zone tubular resistance furnace. Appropriate temperature gradients of 12~15°C/cm at the growth interface and stable thermal profile were obtained. A crack-free ZnGeP2 single crystal with size of Φ15mm×30mm was grown successfully in the furnace mentioned above. The as-grown crystal was characterized by X-ray diffraction (XRD) and Infrared (IR) spectrophotometers. It is found that there is a cleavage face of (101) and X-ray multiple diffraction peaks of the {101} faces are observed, The infrared transmission of a ZnGeP2 wafer of 3 mm thickness is about 50% in the region of 3~10μm. These results show the designed crystal growth furnace is suitable for growth of ZnGeP2 crystal, and the as-grown ZnGeP2 crystal has good structural integrity and high quality.

Numerical Simulations and Experimental Investigations on Lead Iodide Single Crystals Growth

Authors: Jing Liu, Yu Zhang

Abstract: Lead iodide (PbI₂) single crystal for room temperature radiation detectors are mainly produced by Vertical Bridgman (VB) method. Computer simulations of the VB method could be an effective tool to optimize the growth process and reduce the production costs. In the present study, we applied the general Computational Fluid Dynamics (CFD) code to solute the quasi-static two-dimensional (2D) axisymmetric model of the VB ampoule filled with PbI₂ melt and direct the growth of high quality PbI₂ single crystals with a diameter of 15 mm. The thermal conductivity and latent heat generation during the crystallization is considered in the numerical model. We focused on the crystal-melt interface deflection. The results demonstrated that the ampoule with 15 mm diameter is better than that of 30 mm. The experimental results showed that the single crystal with 15 mm diameter exhibited high electrical resistivity (10⁹ Ωcm).
