Prof. LeBeau’s Research on Distortions in Atomic Structure of Materials

Prof. James LeBeau’s group are using a technique they developed with FEI Titan G2 80-300 to observe minute distortions in the atomic structure of complex materials, shedding light on what causes these distortions and opening the door to studies on how much atomic-scale variations can influence a material’s properties.

The paper, “Direct observation of charge mediated lattice distortions in complex oxide solid solutions,” was published online Feb. 13 in Applied Physics Letters. Lead author of the paper is Dr. Xiahan Sang, a postdoctoral researcher at NC State.

Apr 17th, 2015 – Basic Vacuum Technology Short Course


Date Friday, April 17th, 2015
Time  8:30 am – 5:00 pm
Location Monteith Research Center, Rm 320 (NCSU Centennial Campus)
Instructor Fred Stevie
Registration Cost (Students) $50
Registration Cost (Industry) $150

This is primarily a hands on course with some lecture time. Individuals will work on two functioning vacuum systems. Each attendee will manually remove and install components to learn practical knowledge when dealing with vacuum systems. Covered components include forepumps, turbomolecular pumps, ion pumps, thermocouple and cold cathode gauges, valves, flanges, and feedthroughs.

In addition to hands-on instruction, attendees will receive the following:

  • Digital copy of lecture materials
  • Tour of AIF facility


The course instructor will be Fred Stevie. Fred has 40 years of experience with vacuum instrumentation and is an American Vacuum Society instructor. He is currently responsible for the Surface Analysis Laboratory at NC State.


March 13th, 2015 – FIB Short Course

FIB short course

AIF is going to offer another FIB short course in March 13th, 2015. The FIB short course includes lectures covering an introduction to the FIB technique, an overview of the principles and operation of the FIB as well as applications such as FIB prepared SEM and TEM cross section. Also, there will be hands on demos of these applications on the AIF Quanta Dual Beam FIB-SEM. To insure each student receives a maximum of time on the FIB, the course will be limited to 6 participants.

Date Friday, March 12th 2015
Time 8:30 am – 5:30 pm
Location 324 Monteith Research Center, NCSU Centennial Campus
Registration cost (student) $50
Registration cost (industry) $150
