本文报道ZnSe基ⅡⅥ族宽带发光材料分子束外延系统的建立、p型掺杂用等离子体活性氮源的研制、两性掺杂的ZnSe材料的生长。实验证明国产MBE设备能够自洽生长优质ZnSe单晶薄膜;用自制的等离子体活性氮源作受主掺杂剂,获得了pZnSe单晶薄膜,经CV测量发现,[Na][Nd]高达~5×1017·cm-3;用国产粉末状ZnCl2源作施主掺杂剂,获得了nZnSe单晶薄膜,Hal测量表明[n]高达~23×1019·cm-3。生长速度均控制在~05μm/h。
This paper reports the development of molecular beam epitaxy system of ZnSe groupⅡ-Ⅵ broad-band luminescent materials, the development of plasma-active nitrogen source for p-type doping, and the growth of amphiphilic ZnSe materials. Experiments show that domestic MBE equipment can self-consistent growth of high-quality ZnSe single crystal thin film; home-made plasma active nitrogen source as acceptor dopant, obtained p ZnSe single crystal thin film measured by C V found [Na] [Nd] up to ~ 5 × 1017 cm-3; with domestic powder ZnCl2 source as the donor dopant, obtained n ZnSe single crystal film, Hal measurements show that [n] up to ~ 2 3 × 1019 · cm- 3. Growth rate is controlled at ~ 0 5μm / h.
