PTIR combines the spatial resolution of AFM with the specificity of absorption spectroscopy

Nano-Chemical Imaging and -Spectroscopy (IR, nIR, VIS)

Ongoing
The aim of this project is twofold: 1) improve the PTIR measurement (spectral range, signal to noise ratio, throughput, time resolution, information content, range of environmental conditions) and 2) apply PTIR to characterize nanomaterials in important applications. Examples or recent PTIR

DNA Origami for Precise Manufacturing of Nanoscale Structures

Completed
The base pairing of adenine to thymine and guanine to cytosine to form DNA provides a robust molecular recognition scheme that can be used to create a wide variety of well-ordered nanostructures. DNA origami, which uses a long scaffold strand folded together by specific sets of short staple strands

Modeling and Simulation of Nanofabrication (Archived)

Completed
While self-assembly is still in its relative infancy with respect to practical use, with much additional research required to reach maturity, the more widely utilized top-down methods will continue to require advances and modifications to improve current nanomanufacturing techniques. This modeling

Probing Graphene Electronic Devices with Atomic Scale Measurements

Ongoing
Two of the remarkable features of graphene that are opening avenues to multiple applications are its high transport carrier mobility and the broad tunability of its electronic properties. Graphene charge carriers can be tuned continuously from negative carriers (i.e., electrons), to positive (holes)
