In this work, electron beam induced current (EBIC) and scanning photocurrent microscopy (SPCM) were used to quantitatively investigate the electronic properties of silicon nanowire devices. For the first time, it was shown that minority carrier diffusion lengths in phosphorous-doped silicon nanowires are significantly reduced from their bulk values because of...
In the United States and around the world, the growing energy demands and climate concerns necessitate renewable and efficient energy production. Thermoelectric materials could be one small part of this larger picture movement, but their high cost and low efficiency must be improved to realize commercial use. To decrease the...
