CNM Short Courses — Thursday, May 9, 2013
All courses meet 8:30 am to 12:00 pm
Course A also meets 1:30 - 5:00 pm
Modeling and Simulation of Nanofabrication Processes, Bldg. 440, Rm. A105-106 (full day)
Course B: Confocal Raman Spectroscopy, Bldg. 440, Rm. B108 (morning)
Course C: Using the Hard X-Ray Nanoprobe, Sector 26 Control Room (morning)
Course D: High-performance Computing Techniques for Materials Modeling and Nanophotonics, Bldg. 440, Rm. A201 (morning)
The current drive for enhanced device functionality and power pushes modern nanofabrication processing to its limits, where it becomes necessary to understand the influences of each process variable and to maxiemiz processing latitudes. Simulation programs are key to this effort. In the case of industrial processes, simulation packages are already available, but at nano- and mesoscopic scales, such programs have to be developed. This short course will cover topics ranging from block-copolymer, hydrogel, and wet etching simulations to process control software demonstration. A hands-on demonstration of the process control software will take place in the afternoon.
A hands-on demonstration of the capabilities of the CNM's confocal Raman microscope will be presented. Subjects to be discussed and demonstrated include:
- Basic Raman spectroscopy concepts
- Anatomy of a confocal Raman microscope
- Sample preparation
- Simple spectra collection
- Effects of excitation wavelength
- Point mapping
- Line/area mapping
Attendees are encouraged to bring a sample of interest; please contact the instructor David Gosztola (firstname.lastname@example.org) for sample limitations prior to arrival.
This course will consist of a functional overview of the nanoscale hard x-ray microscopy capabilities at the CNM/APS Hard X-ray Nanoprobe beamline. A step-by-step description of the basic experimental process steps—including sample requirements, sample preparation, alignment, data collection, and data analysis—will be provided through the use of demonstration experiments and data. A survey of recent literature and current experimental directions will also be presented to highlight the scientific impact of these unique imaging capabilities. This course is targeted for potential CNM users interested in a working understanding of the experimental strengths and functional requirements of the nanoprobe instrument.
Topics will include
- Scanning x-ray fluorescence microscopy
- Scanning x-ray diffraction microscopy
- Bragg projection ptychography
- Full-field transmission x-ray microscopy
- Computed x-ray tomography
This course will provide an introduction to the CNM high-performance computing cluster, covering remote access, basic usage, and applications in several fields.
We will give an overview on materials modeling and visualization techniques, with examples of using key applications from the fields of first principle density functional theory (e.g. VASP), classical molecular dynamics (LAMMPS), and nanophotonics (FDTD/Lumerical). For each field, we will review the theory, show a practical example of preparing inputs for a run, submit a job, and finally how to inspect and analyze the results.
