| Research Abstract |
In this study, ZnSnP_2 was proposed as a new material for solar cells. First, the phase diagram of the Zn-Sn-P ternary system was experimentally established and bulk crystals of ZnSnP_2 were fabricated based on the diagram. The evaluation of the degree of order was carried out using X-ray diffraction and it was clarified that the degree of order decreases with increasing temperature, that was expected from thermodynamics. Finally, the information on carriers were obtained by investigating optical and electrical properties using samples after crystal growth. The fundamental studies were established to obtain a relationship between the order-disorder transition and semiconductor properties.
