Description

Harvesting the wasted heat released in the atmosphere by electronic devices has become an important issue in microelectronics as devices shrink toward nanoscale dimensions while achieving an increase in operating speed. Spintronic devices that make use of electrons’ spin as an information carrier offer a promising path to create novel efficient devices thus reducing this wasted heat. Thermoelectronics, on the other hand, explores the possibility of converting heat into electrical power. Spin caloritronics is an exciting new research field that takes advantage of both spintronics and thermoelectronics. In this talk, I will present the design of a spin caloritronic device that consists in ferromagnetic/oxide/semiconductor multilayer configuration. I will describe how this device can harvest wasted heat by making use of the newly discovered Seebeck spin tunneling effect.
