Importance of grain size for nanostructured poly-Si thermoelectric material
Abstract: Silicon thermoelectric device is one of the promising energy harvesters due to its compatibility with current semiconductor technology and environment, and various types of nanostructured silicon are studied to improve thermoelectric efficiency. In this work, we investigate thermoelectric performance of poly-Si membranes with PnC nanopatterning. The results show that PnC patterning reduces the thermal conductivity of membranes by 60 %, and grain size control enables more efficient reduction. These effects of nanostructure and grain can be combined, and important for high thermoelectric material efficiency
