Abstract:
Energy efficient solid state
electronic devices that are  made of clean and non-hazardous materials are
essential. The seminar  will revolve around this central theme: energy
efficient devices, clean  semiconductors and energy harvesting.
Research on efficient light  emitters using the abundant and exciting
III-Nitride materials will be  presented. Although we can increase
efficiency of electronics using  novel paradigms of operation, we cannot
completely eliminate losses.  While heat is dissipated in all activities
leading to loss of useful  resources, we can also recover the lost energy
by scavenging the heat  and transforming it to useful electricity. This
type of harvesters  employ the Seebeck effect to generate electricity.
Recent work on the  Silicon based engineered thermoelectric material will
be presented as  well. The engineered material has the potential to find
widespread  applications for waste heat recovery, especially in smart
windows and  wearable electronics, to supply low-power devices.
