Wake Forest University Regional Microscopy Facility
Managed by NANOTECH

Welcome to the Wake Forest University Regional Microscopy Facility. This user facility serves the research community of Wake Forest University as well as the research and engineering communities of the western Carolinas.  The facility specializes in advanced imaging techniques for biological and bio-medically relevant materials, composite materials, interfaces, polycrystalline materials, and nanophase materials.  We are housed in two laboratories: the Deacon Blvd. research facility and the Hanes Building on the Bowman Gray Campus. The facility offers HRTEM, CTEM, FE-SEM, SEM, and a variety of scanning probe microscopies. 

The facility is managed by the Center for Nanotechnology and Molecular Materials at Wake Forest University

Scanning Probe Microscopy

 

afm
Jeol 5200

(Description from the Jeol web site)

The JSPM-5200 can be configured as either an atomic force microscope (AFM) or scanning tunneling microscope ( STM ) by merely changing the tip. STM modes include CITS, I-V, S-V, and I-S. Standard AFM modes include contact, friction force microscopy, current image, non-contact and discrete contact with either slope detection or frequency detection, and phase imaging.

 
stm Scanning Tunneling Microscopy (STM)
RHK

This microscope was developed in cooperation with RHK Technology, Inc.   It is equipped with a cryostat.  The ultra high vacuum system was custom designed and built by Duniway Stockroom Corp.    Further, this STM uses quite low tunneling currents with imaging having been achieved at  tunnel currents below 1 pA.  The system is ideal for studies of nanostructures which might otherwise be damaged by the large field densities wihin the tunneling junction.  Modifications are constantly being made to this machine as we develop new techniques for high precision determinations of electronic phenomena in nanostructures.
