PIEZOELECTRIC AND SEMICONDUCTING COUPLED NANOGENERATORS

摘要

An electrical generator (100) includes a substrate (110), a semiconductor piezoelectric structure (120) having a first end (122) and an opposite second end (124) disposed adjacent to the substrate (110), a first conductive contact (210) and a second conductive contact (212). The structure (120) bends when a force is applied adjacent to the first end (122), thereby causing an electrical potential difference to exist between a first side (126) and a second side (128) of the structure (120). The first conductive contact (210) is in electrical communication with the first end (122) and includes a material that creates a Schottky barrier between a portion of the first end (122) of the structure (120) and the first conductive contact (210). The fist conductive contact (210) is also disposed relative to the structure (120) in a position so that the Schottky barrier is forward biased when the structure (120) is deformed, thereby allowing current to flow from the first conductive (130) contact into the first end (122).
