Perched atop a high plateau in Chile’s Atacama Desert, a long-awaited observatory is beginning to take shape: the largest suite of ground-based telescopes
The goal of this project is to help develop innovative metrologies and measurement protocols for micro/nano-scale analysis of particles.
In this project, state-of-the-art optical and electron-based microscopy are used to conduct research for quantitative and qualitative analysis of chemical
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
Manipulation of single atoms with the scanning tunneling microscope is made possible through the controlled and tunable interaction between the atoms at the end of the STM probe tip and the single atom (adatom) on a surface that is being manipulated. In the STM tunneling junction used for atom
This project is developing atomically precise, atom-based electronic devices for use in quantum information processing and analog quantum simulation. We are developing the fabrication, measurement, and modeling methods needed to realize single atom, spin-based qubits in silicon as an integrated
Deposition of carbonaceous material under electron beam irradiation is an old and persistent problem of scanning electron microscopy. It is an impediment to

The design and implementation of dopant-based silicon nanoscale devices rely heavily on knowing precisely the locations of phosphorous dopants in their host
An electron hologram is a fringe modulated image containing the amplitude and phase information of an electron transparent object. The HolograFREE routines
LEAP 4000X Si/HR Imaging time-of-flight mass spectrometer and field ion microscope. Can deliver 3-D, isotopically- and chemically- resolved images Sub-nanometer
The NIST transition edge sensor microcalorimeter is energy dispersive x-ray spectrometer capable of ~5 eV resolution over a range of energies from hundreds to
Field evaporates (with a voltage and laser pulse) a sharp tip-shaped specimen. Collects the ionization products in a position-sensitive, time-of-flight mass
