Fabrication of high gauge factor piezoresistive nanocrystalline Si film using aluminum-induced crystallization of HWCVD deposited a-Si:H

Abstract: Aluminum-induced crystallization (AIC) has been used to achieve device quality nc-Si thin films, at annealing temperatures ranging from 300 to 450°C, exhibiting electronic properties favourable for piezoresistive microelectromechanical systems sensor application. The nc-Si films obtained by AIC at an annealing temperature of 400°C showed hole concentration of the order of 10 18 cm −3 and the Hall mobility was measured to be 13.5 cm 2 V −1 s −1 . The films were subjected to piezoresistive gauge factor measureme… Show more
