Measuring Intermolecular Interactions with Electro-Acoustic Spectroscopy

Ongoing
We have a number of opportunities to collaborate with us. See below for details. What does this project aim to do for the chemical industry? Many industrial processes depend on the intermolecular environment- the solvents and ions that surround a molecule. These interactions impact separations

Integrated CMOS Testbeds for Nanoelectronics and Machine Learning

Ongoing
The increasingly complex device requirements for next-generation computing architectures such as neuromorphic computing or nanoelectronic machine learning accelerators present challenges for researchers across the spectrum of institutions, from small businesses and universities to government

Hybrid Quantum Optomechanical Systems with Solid-State Artificial Atoms

Ongoing
Quantum Dot – Surface Acoustic Wave Microwave-to-Optical Transducers In this project, we focus on coupling nanoscale acoustic resonators with InAs quantum dot (QD) single photon sources (Fig. 1). At ultra-low temperatures, such as those in a dilution refrigerator, the acoustic resonators act as
