个人简介

Holger Kleinke's research focuses on finding and optimizing new thermoelectric materials. Thermoelectrics are capable of converting heat into electrical energy and vice versa. This environmentally friendly energy conversion currently has several applications, but is limited by its low efficiency. His research group is attempting to increase the efficiency so that thermoelectrics may be used to recover electricity from the nowadays abundant waste heat, e.g. in the exhaust of automobiles.

研究领域

One of Holger Kleinke's newest projects is to utilize Cu ion mobility to lower the thermal conductivity of thermoelectric materials. This mobility has to be localized within each unit cell in order to inhibit Cu ion migration throughout the material, which would otherwise cause device degradation. Since the thermoelectric properties depend on the thermopower as well as on the electrical and thermal conductivity, various property measurements are routinely carried out in the group. The syntheses are guided by calculations performed by students who are fascinated by the theoretical aspects of chemical research.
