beamline:
	34ID-C

collaboration:
	No

contact:
	ikr@uiuc.edu

days:
	6

description:
	Coherent X-ray diffraction will be used to investigate the structure of a few ML Ge grown on Si(124).  The miscut Si(124) surface spontaneously facets into a grooved morphology onto which the Ge aligns itself into crystalline wires.  The size distribution of the wires will be determined from the shape of the Ge diffraction peak.  The homogeneity will be investigated by scanning the sample through the focus of the KB mirrors.

equipment_required:
	KB mirrors.  (Uncoated)

experiment:
	Germanium nanowires

foreign_nationals:
	

hazards:
	Samples are all prefabricated at MRL and will be returned to the grower after the experiment.

instrument:
	34ID-C coherent

instrument_other:
	

minimumdays:
	4

name:
	Ian Robinson

new_request:
	ON

nonmembers:
	

unacceptable_dates:
	Preferred dates Nov 3-8.
Unacceptable before Oct 27 or after Nov 20.

z34ID_change_undulator:
	no

z34ID_details:
	It might be interesting to run ONE DAY at 11 keV (Ge-K), which is not normally usable by 34-ID-E.

z34ID_parasitic:
	yes
