Scientists from Indian Institute of Technology, Bombay, find a way to convert undesirable heat energy from electronic devices to electricity and reconverting this into electricity using the concept of thermoelectric effect - a physical phenomenon where a difference in the temperature between two contacts leads to a difference in the voltage, and hence flow of electricity.
A unique material, chromium antimonide (CrSb), defies conventional rules by conducting electricity like two different materials in one, dominated by electrons in one direction and holes in another, a phenomenon called DDCP.
