With the need for newer materials being utilised to substitute the over reliance of common materials, more kinds of materials are being used. Some of these materials are still relatively new in discovery, thus their properties are still unknown. The plan for this project is to find out the thermoelectric properties of some of these materials by using a Janis Cryostat. It has been shown through past research that thermoelectric materials can increase energy efficiency. In today’s world, an apparent challenge that humans need to solve is the energy crisis, where fossil fuel reserves are being depleted. Thermoelectric materials can be used to develop new cooling methods and help to convert waste heat energy into electrical energy. The project involves the use of a sample holder secured to the Janis Cryostat. This sample holder would hold the chip containing the different materials and this whole setup would be tested under a temperature range from 77K to 700K. Through these tests, the Seebeck Coefficient and Electrical Conductivity of these materials would be studied for practical usage. The system must be electrically insulative, thermally conductive and physically durable. From this project, hopefully thermoelectric properties of some of these materials would be found.
