Department(s)/lab(s): School of Physics | Micolich Nanoelectronics Group @ UNSW
Summary:

Micolich works on semiconductor nanowire and organic/polymer nanoelectronic devices, with two strands relevant here: the physics of low-dimensional transport and noise in nanowire transistors, and the use of those devices as transducers at the interface with biological systems, where a nanowire field-effect transistor acts as an extremely local potentiometer sensitive to charge and potential changes at the cell membrane. The group has a strong record in noise spectroscopy — using 1/f and random telegraph noise as a diagnostic rather than a nuisance. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — nanowire FET bioelectronic sensing is the principal electrical competitor to NV-based bio-magnetometry: both aim to read out cellular electrophysiology without patch-clamping, one via magnetic fields at pT/sqrt(Hz), the other via local potential. Borderline inclusion, kept because the bio-interface sensing thread is genuine.

Department(s)/lab(s): Materials Science and Engineering | Minor Group (National Center for Electron Microscopy) @ UCB
Summary:

Minor directs the National Center for Electron Microscopy at LBNL and develops in-situ TEM methods to observe how materials deform, fracture, and transform under mechanical load, temperature, and other stimuli in real time at atomic resolution.

Department(s)/lab(s): Chemistry / PME | Park Group (Jiwoong) @ UChicago
Summary:

Studies atomically thin 2D quantum materials and their sensing applications. Directions: (1) tr-ARPES and ultrafast spectroscopy of non-equilibrium electronic dynamics in TMDs and graphene heterostructures; (2) 2D material nanophotonic devices for light sensing and emission; (3) wafer-scale CVD growth of hBN, MoS2, WSe2 for integrated quantum devices; (4) scanning probe characterization of local optical and electronic properties. Key tool: time-resolved photoemission as ultrafast electronic structure sensing.

Department(s)/lab(s): Materials Science and Engineering | M. Scott Electron Microscopy Lab @ UCB
Summary:

Scott uses and develops 4D-STEM (scanning nanobeam electron diffraction) and other advanced electron-microscopy modalities, including energy-filtered techniques, to map short-range structural order and local diffraction signatures in quantum and semiconductor materials at the nanoscale.

Department(s)/lab(s): School of Chemistry | Tilley Nanomaterials and Electron Microscopy Group @ UNSW
Summary:

Tilley directs the UNSW Electron Microscope Unit and runs a nanomaterials group whose distinctive capability is in-situ liquid-cell TEM: watching nanoparticle nucleation, growth and catalytic transformation in real time inside the microscope, in liquid, rather than inferring mechanism from before-and-after snapshots. The synthetic side produces magnetic and plasmonic nanoparticles used as biosensor labels and MRI contrast agents, largely in collaboration with Gooding and Reece. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — the group is a supplier and characteriser of the nanoparticle probes that in-cell quantum sensing depends on — including the magnetic-nanoparticle labels whose stray fields a pT/sqrt(Hz) NV sensor would actually detect — and the liquid-cell TEM capability is a rare way to validate what those particles are doing in situ. Borderline inclusion (materials characterisation rather than sensing), kept for the collaborative infrastructure it represents.

Department(s)/lab(s): PME | Yang Group (Shuolong) @ UChicago
Summary:

Uses MBE thin-film growth combined with equilibrium and non-equilibrium ARPES to sense electronic structure at material interfaces. Directions: (1) non-equilibrium photoemission (tr-ARPES) to map ultrafast electron dynamics in topological and superconducting materials; (2) MBE engineering of interfacial superconductivity and topological orders at oxide and chalcogenide interfaces; (3) light-induced phase transitions probed by ultrafast ARPES as a sensing modality for correlated electron dynamics.

Department(s)/lab(s): Materials Science and Engineering | H. Zheng Group (LBNL) @ UCB
Summary:

Zheng develops in-situ liquid-cell transmission electron microscopy to directly observe nanocrystal nucleation, growth, and chemical transformation in solution with nanometer spatial and sub-second temporal resolution, capturing dynamic processes invisible to static microscopy.
