High-carrier-mobility semiconductors on flexible-plastic are essential to realize flexible electronics, for this purpose, electrical properties of orientation-controlled large-grain Cie crystals on flexible-plastic dircctly formed by nucleation-controlled gold-induced-crystallization (GIC) are examined, and compared with those obtained by aluminum-induced-crystallization (AIC). The Ge crystals show p- Type conductions. Here, hole concentrations are 2.2 x1017 and 5.8 x 1020cm 3 for GIC-Ge and AIC-Ge, respectively, which are explained on the basis of the solubility of Au and AL in Ge. Thanks to the low hole concentration, GIC-Ge shows high hole mobility (160cm2V-1 'S-1') compared with AIC-Ge (37cm2V-1 'S-1'). These demonstrate significant advantage of GIC to realize high-performance flexible-electronics.
