摘要

In situ energy supply method has a high demand for the various distributed devices in the fast-developing Internet of Things. Harvesting energy from the environment that converts mechanical energy into electricity has emerged as a promising candidate for in situ energy network. However, although hardly achieved, electricity is much more desired under low temperature environments, such as the north pole or on Mars. Here, it is reported that the dynamic Schottky diode can work well under a low temperature of 77 K, while the electricity output can be greatly increased compared with that at room temperature. The voltage and current output can be increased to 1.21 V and 11.38 mu A compared to 0.76 V and 4.86 mu A at room temperature, the higher carrier mobility at a lower temperature is responsible for this improvement. This research passes the way for power generation in some extreme cold areas, which can further promote the practical application of dynamic diode generators.
