Needle in a haystack: efficiently finding atomically defined quantum dots for electrostatic force microscopy
José Bustamante, Yoichi Miyahara, Logan Fairgrieve-Park +5
The ongoing development of single electron, nano and atomic scale semiconductor devices would benefit greatly from a characterization tool capable of detecting single electron char…
Spatially resolved random telegraph fluctuations of a single trap at the Si/SiO2 interface
Megan Cowie, Procopios C. Constantinou, Neil J. Curson +2
We use electrostatic force microscopy to spatially resolve random telegraph noise at the Si/SiO interface. Our measurements demonstrate that two-state fluctuations are localize…
Single-Atom Control of Arsenic Incorporation in Silicon for High-Yield Artificial Lattice Fabrication
Taylor J. Z. Stock, Oliver Warschkow, Procopios C. Constantinou +3
Artificial lattices constructed from individual dopant atoms within a semiconductor crystal hold promise to provide novel materials with tailored electronic, magnetic, and optical…
Detection Sensitivity Limit of Hundreds of Atoms with X-Ray Fluorescence Microscopy
Mateus G. Masteghin, Toussaint Gervais, Steven K. Clowes +10
We report X-ray fluorescence (XRF) imaging of nanoscale inclusions of impurities for quantum technology. A very bright diffraction-limited focus of the X-ray beam produces very hig…
Resistless EUV lithography: photon-induced oxide patterning on silicon
Li-Ting Tseng, Prajith Karadan, Dimitrios Kazazis +7
In this work, we show the feasibility of extreme ultraviolet (EUV) patterning on an HF-treated Si(100) surface in the absence of a photoresist. EUV lithography is the leading litho…
Momentum-space imaging of ultra-thin electron liquids in delta-doped silicon
Procopios Constantinou, Taylor J. Z. Stock, Eleanor Crane +11
Two-dimensional dopant layers (-layers) in semiconductors provide the high-mobility electron liquids (2DELs) needed for nanoscale quantum-electronic devices. Key parameters such…
