Prof. Feng gives an invited talk at the 3rd Berkeley Symposium on Energy Efficient Electronic Systems (E3S) – reporting on our team’s robust SiC NEMS logic devices with high performance and long lifetime.
Thanks to the warm invitation from Berkeley E3S Center’s Director Prof. Eli Yablonovitch and all the organizers for this very nice symposium!

[July 2013] [Conference] [Best Paper Competition Finalists]
Members of the group (Hamid, Jaesung, Max) give several presentations at the 2013 Joint UFFC, EFTF and PFM Symposium.  Our presentations are in the 2013 Joint European Frequency & Time Forum (EFTF) & International Frequency Control Symposium (EFTF-IFCS 2013).   
As finalists for student paper competition, Hamid and Jaesung each presents both a talk and a poster for the paper competition.  Go Hamid & Jaesung!
All of us have enjoyed the beautiful city of Prague and the Vltava river~~  If you also love music – here is Vltava by Smetana you can enjoy too.
