The Nanoengineering Laboratory works across the technical areas of nanotechnology, instrumentation, materials science, thermal transport, and micro- and nano-manufacturing.  We take a broad view towards aligning our work across the domains of science, technology, and commerce.   Researchers join the Nanoengineering Laboratory to develop their skills for understanding scientific fundamentals, advancing the state of the art technology, and seeking translational impact.

Applied Physics Letters has featured a paper by Professor William P. King and Patrick C. Fletcher, formerly of King’s research group, as the most downloaded paper on the site over the past four months. This paper is based on Dr. Fletcher’s work on electron emission using the pyroelectric effect from 30 nm thick films of PbZrxTi1-xO3 (PZT).

Researchers at Dr. King’s group have measured nanometer-scale infrared absorption in semiconductor plasmonic microparticles using a technique that combines atomic force microscopy with infrared spectroscopy. The ability to directly measure the plasmonic behavior within individual microparticles will allow researchers to design and test more complex optical materials. Paper available here.

Researchers at Dr. King’s group have developed fast charging microbatteries with very high power and energy densities via 3D microstructured electrodes and novel battery chemistry. Paper available here.

Researchers in Dr. King’s group measured the chemical properties of polymer nanostructures as small as 15 nm using a novel technique called atomic force microscope infrared spectroscopy (AFM-IR). Paper available here.

Researchers at the University of Illinois, University of Pennsylvania, and Advanced Diamond Technologies Inc., have created a new type of nano-tip made entirely out of diamond.  The tip can be used for nanometer-scale thermal processing, and it is extremely resistant to wear and contamination. Paper available here.

Dr. William P. King has been named the director of the National Science Foundation (NSF)-Funded Center for Nanoscale Chemical-Electrical-Mechanical Manufacturing (Nano-CEMMS).

Nanotechnology-based materials identification enables critically needed chemical metrology for nano-manufacturing. A group of researchers in Dr. King’s group and at Anasys Instruments used atomic force microscope based infrared spectroscopy (AFM-IR) to characterize polymer nanostructures and systems of integrated polymer nanostructures. Publication available here.

Researchers at Dr. King’s group have developed an electro-thermal cantilever probe capable of independent control of both the bias as well as the temperature at the probe tip. Publication available here.

With the first observation of thermoelectric effects at graphene contacts, a team of researchers led by William King and Eric Pop found that graphene transistors have a nanoscale cooling effect that reduces their temperature. Publication available here.
