Funding:

Our group's research is generously funded by DOE-BES, NSF CAREER, AFOSR-MURI, Hellman Foundation, Argonne LDRD as well as internal UCSD funding sources.

Group Calendar:

• UCSD Physics Department Seminars

• Group Meetings: Fridays (for now) at 1:00 PM in Mayer 5623
  • Presentation schedule (subject to change abruptly and without notice):
    • 7/15 Return of the group meeting
    • 7/22 Sebastian - "Spin-Based Digital Logic" - Abstract: With the use of personal computers and other electronics becoming more wide spread, energy consumption of these devices is becoming a large portion of all electricity used. Spin-based electronics is a solution that could greatly reduce this problem in the near future, while allowing us to reduced integrated circuitry size. A review of "spintronics" will be given, including recent work of generating pure spin currents and spin injection into semiconductors. Finally, a scheme for creating pure spin-based digital logic devices will be discussed.
