Thus there are fewer dislocations in my beam size. Wenge Yang has done microbeam diffraction experiment on the same sample in APS sector34ID-E. I will use mirrors to focus the beam to micron size and beam is grazing incidence to the sample surface. I'm interested in the coherent diffraction pattern from the dislocations at the GeSi/Si interfaces. Also I will try some new samples such as Ge nanowire on Si substrate and Quantum dots sample. equipment_required: KB mirrors experiment: Coherent diffraction from dislocations and strain in GeSi/Si interfaces foreign_nationals: Yang Da hazards: none instrument: 34ID-C coherent instrument_other: minimumdays: 5 name: Yang Da nonmembers: unacceptable_dates: z34ID_change_undulator: no z34ID_details: z34ID_parasitic: yes #REMOTE_HOST: yang-m.mrl.uiuc.edu #REMOTE_ADDR: 130.126.101.162 #CONTENT_LENGTH: 977 #HTTP_REFERER: http://www.uni.aps.anl.gov/unireq.htm #HTTP_USER_AGENT: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)
