———————Mini Seminar on May 15———————
Keio-TU Munchen special mini seminar on semiconductor optoelectronics
Wednesday, May 15, 2013, 1:30pm-3:30pm
Keio University Yagami Campus, Soso-Kan (bldg. 14), Discussion Room 2

1st presentation, 1:30pm-2:30pm
Dr. Gregor Koblmueller (Group Leader III-V Materials, Walter Schottky Institute, TU Munich)
“Growth, structure-property correlations and device prospects of (In, Ga, Al)-As nanowires on Si”

III-V semiconductor nanowires (NW) exhibit significant potential to drive new applicat­ions in nano-electronic and -photonic devices due to their unique properties and possibility for integration on low-cost silicon (Si) plat­form. In this talk, I will review our recent work on the growth and properties of (In,Ga,Al)As-based NWs on Si (111). In particular, I will highlight microstructure-electronic function relationships and show how the optical emission and electrical transport of these structures can be tuned by e.g. the underlying crystal phase, size quantum confinement, complex core-shell strategies, etc. Finally, two specific NW-based device concepts will be introduced, i.e., NW laser and III-V-on-Si NW-tunneling field effect transistor, and first results presented.

2nd presentation, 2:45pm-3:30pm
Dr. Asako Hirai (Senior R&D Scientist at Osram Opto Semiconductors)
