主讲内容：

Spintronics represents a new paradigm of electronics that utilizes both the electron’s charge as well as its spin degrees of freedom. It has the potential to facilitate a new generation of devices possessing high-speed, large memory and ultra-low power consumption. The most critical step in the functioning of a spintronic device is the injection and detection of spin-polarized carriers at the ferromagnet-semiconductor interface. Despite considerable efforts, efficient injection of spins into nonmagnetic semiconductors still continues to be a major hurdle in this field. In this talk, I will present some of our very exciting research going on in this field in my group at the University of Utah. Particular focus will be on the injection and detection of spin polarized carriers in semiconductors using electrical and thermal routes. In the later part of my talk, I will also discuss about new oxide-based 2D material systems being investigated in our laboratory.
