- R. G. Herb Condensed Matter Seminar
- Scotch Tape Method: Not just for Graphene
- Time: 10:00 am
- Place: 5310 Chamberlin
- Speaker: Ken Burch, University of Toronto
- Abstract: Recently mechanical exfoliation has received a great deal attention (2010 Physics Nobel) for producing single atomic sheets of graphene. However this method is incredibly flexible and has opened a new route to producing materials on the nanoscale. Materials with Nanometer thickness are an appealing platform for devices as well as exploring the roles of dimensionality, disorder, and free carrier density in complex materials. To this end we have produced exfoliated crystals of Bi2Sr2CaCu2O8 and Bi2Se3 on a variety of substrates. I will discuss unique advantages of this technique as well as some of the challenges it posses. Interestingly we have observed subtle differences in the Raman spectra between the exfoliated and bulk crystals enabling noninvasive determination of thickness (Bi2Se3) and Doping level (Bi-2212).
- Host: Natalia Perkins
- NPAC (Nuclear/Particle/Astro/Cosmo) Forum
- Predicting Antineutrino Flux with DRAGON
- Time: 4:00 pm
- Place: 4274 Chamberlin
- Speaker: Christopher Jones, MIT
- Abstract: Simulation of a nuclear reactor is extremely important for Double Chooz, an antineutrino experiment whose goal is to extract theta_{13}, and for noninvasive nuclear nonproliferation. An overview of Double Chooz and reactor physics will be given, along with a summary of reactor simulation efforts and code validation. The seminar will conclude with a discussion about the role of simulations in nonproliferation scenarios
