Facilities
Our laboratory is housed on the G and B levels of the LISE (Laboratory for Integrated Science and Engineering) building, as well as the B level of Pierce Hall. It features state-of-the-art equipment dedicated to the fabrication, imaging, and characterization of nanoscale structures and quantum materials, with a specialized emphasis on advanced scanning near-field microscopy techniques (e.g., cryogenic s-SNOM).
Complementary characterization tools include a broad suite of scanning probe microscopies (AFM, PFM, MFM, KPFM, STM, PiFM, AFM‑IR), as well as TEM, SEM, EDX, XRD, XPS, SIMS, EELS, SQUID magnetometry, Raman spectroscopy, ellipsometry, ultrafast pump–probe, and nonlinear spectroscopies.
As part of Harvard’s Center for Nanoscale Systems (CNS), we also leverage a variety of shared research facilities, including the Harvard Laukien-Purcell Instrumentation Center, the Harvard Center for Crystallographic Studies, and the Oak Ridge National Laboratory’s Center for Nanophase Materials Sciences (CNMS), among others.

At Harvard, we established the university’s first cryogenic s-SNOM system to investigate novel phenomena in low-dimensional quantum materials. This platform uniquely integrates state-of-the-art s-SNOM technology with cryogenic capabilities, broadband laser sources, and in situ electric fields—making it one of fewer than 20 such systems worldwide. It enables comprehensive analysis of quantum materials across multiple length, frequency, and energy scales, which is crucial for probing quasiparticle reconstruction, topology, and correlated-electron excitations.
