Since the first computers were developed, their performance has mainly depended on increasing the density of transistors on monolithic chips. However, as we...
Project activities include: Electronic structure of semiconductor-oxide interfaces. Thermodynamics of flexible microporous materials for gas storage Gas adsorption in microporous materials Analysis of topological materials, including magnetic topological insulators High-throughput screening of...
EPR spectroscopic methods to measure distances in the nanometer range, collectively referred to as pulsed dipolar spectroscopies, have been applied to biomacromolecular systems containing a pair of spin labels (nitroxide spin labels) to determine tertiary/quaternary structures and to follow...
Conventional transmission electron imaging does not necessarily show both strong contrast and high spatial resolution for nanomaterials or soft matter. This is particularly the case for isolated nanostructures or low- Z materials like polymers or biomaterials. For example, consider structures in the...
Atomistic simulations are increasingly being used as a tool to understand and predict properties of materials in systems, such as nanomaterials, where direct measurement is time-consuming or extremely difficult. The success of atomistic simulations depends critically on the fidelity of a specific...
Instrumented indentation (nanoindentation) remains a leading technique for micro- and nanoscale mechanical characterization. Unlike other indenter geometries...

As transistor dimensions approach their physical scaling limits, advanced packaging has emerged as an effective solution to today's challenging demands. Hybrid...
We directly retrieve the coherence properties of a quantum dot including fine-structure splitting (FSS) of a telecom-band quantum dot from a single Hong–Ou...
