Foundry CMOS platform for multimodal quantum materials characterization
Sharad Kumar Yadav, Luca Nessi, Ondrej Dyck +13
Quantum materials experiments increasingly rely on microwave, electrical, thermal, optical, and structural probes, but these capabilities are typically assembled from custom hardwa…
Atomically Precise Electron Beam Sculpting of Bilayer h-BN: The Role of Crystallographic Orientation and Milling Strategy
Ondrej Dyck, Andrew R. Lupini, Ivan Vlassiouk +3
Achieving atomic precision in top-down manufacturing remains a fundamental challenge nanofabrication technology. Here, the focused electron beam of a scanning transmission electron…
Defect Engineering in Large-Scale CVD-Grown Hexagonal Boron Nitride: Formation, Spectroscopy, and Spin Relaxation Dynamics
Ivan V. Vlassiouk, Yueh-Chun Wu, Alexander Puretzky +19
Recently, numerous techniques have been reported for generating optically active defects in exfoliated hexagonal boron nitride (hBN), which hold transformative potential for quantu…
A Versatile Side Entry Laser System for Scanning Transmission Electron Microscopy
Ondrej Dyck, Olugbenga Olunloyo, Kai Xiao +4
We present the design and implementation of a side entry laser system designed for an ultra-high vacuum scanning transmission electron microscope. This system uses a versatile prob…
Your Clean Graphene is Still Not Clean
Ondrej Dyck, Aisha Okmi, Kai Xiao +3
Efforts aimed at scaling fabrication processes to the level of single atoms, dubbed atom-by-atom fabrication or atomic fabrication, invariably encounter the obstacle of atomic scal…
