ENABLING TECHNOLOGY:
Nanotechnology

Few modern advances in science and technology have been as promising as the revolution in nanoscale engineering. The ability to locate, observe, manipulate and fabricate at the molecular and atomic levels has implications for cancer treatments, alternative fuels, solid-state lighting, environmental remediation, high-bandwidth communications, and a host of other endeavors.

Typical Graduate Programs
Graduate students interested in nanotechnology often pursue degrees in areas such as:
Lehigh has long had some of the world's best electron microscopy and spectroscopy facilities. Several recent instrumentation grants from the National Science Foundation have enabled us to refine and improve upon our nanocharacterization capabilities with aberration-corrected scanning transmission electron microscopy, a high-sensitivity low energy ion scattering spectrometer, and a unique device that integrates an inverted optical microscope with an atomic force microscope.

Combined with our current facilities, the new instruments enhance our ability to measure the physical properties and behavior of materials and to correlate their structure and chemistry -- all at the level of the nanometer and the angstrom. They are also helping us study nanomaterials in more dynamic environments while charting their reactivity. In short, they give us capabilities that rival those of any nano research group anywhere.

Lehigh's Center for Advanced Materials and Nanotechnology provides a focal point for research on nanocharacterization, nanoparticles, sustainable nanoengineering, advanced ceramic materials, packaging for microelectronic and optoelectronics, and nanofabrication. Across our programs, Lehigh researchers and graduate students benefit from the breadth and sophistication of our nanotechnology resources -- including our Electron Microscopy Facility, Light Optical Microscopy Facility, Quantitative Image Analysis Facility, Polymer Characterization Laboratory, and Nano and Micro-Mechanical Behavior Laboratory.

Research Spotlight

The research of Masashi Watanabe, associate professor of materials science and engineering, emphasizes materials characterization using various electron microscopy approaches involving analysis via X-rays and energy-loss electrons in analytical electron microscopes and atomic-resolution high angle annular dark-filed (HAADF) imaging in scanning transmission electron microscopes. He developed the ζ (zeta)-factor method for quantitative X-ray analysis and implemented multivariate statistical analysis for spectrum images of X-rays and energy-loss electrons. .
