SiQAD: A Design and Simulation Tool for Atomic Silicon Quantum Dot Circuits
Samuel Ng, Jacob Retallick, Hsi Nien Chiu +7
This paper introduces SiQAD, a computer-aided design tool enabling the rapid design and simulation of atomic silicon dangling bond quantum dot patterns capable of computational log…
Autonomous Scanning Probe Microscopy in-situ Tip Conditioning through Machine Learning
Mohammad Rashidi, Robert A. Wolkow
Atomic scale characterization and manipulation with scanning probe microscopy rely upon the use of an atomically sharp probe. Here we present automated methods based on machine lea…
Resolving and Tuning Carrier Capture Rates at a Single Silicon Atom Gap State
Mohammad Rashidi, Erika Lloyd, Taleana R. Huff +4
We report on tuning the carrier capture events at a single dangling bond (DB) midgap state by varying the substrate temperature, doping type, and doping concentration. All-electron…
Initiating and monitoring the evolution of single electrons within atom-defined structures
Mohammad Rashidi, Wyatt Vine, Thomas Dienel +5
Using a non-contact atomic force microscope we track and manipulate the position of single electrons confined to atomic structures engineered from silicon dangling bonds (DBs) on t…
All-Electronic Nanosecond-Resolved Scanning Tunneling Microscopy: Facilitating the Investigation of Single Dopant Charge Dynamics
Mohammad Rashidi, Wyatt Vine, Jacob A. J. Burgess +5
The miniaturization of semiconductor devices to the scales where small numbers of dopants can control device properties requires the development of new techniques capable of charac…
Atomic White-Out: Enabling Atomic Circuitry Through Mechanically Induced Bonding of Single Hydrogen Atoms to a Silicon Surface
Taleana Huff, Hatem Labidi, Mohammad Rashidi +4
We report the mechanically induced formation of a silicon-hydrogen covalent bond and its application in engineering nanoelectronic devices. We show that using the tip of a non-cont…
Modeling of novel lateral AlGaAs/GaAs quantum well solar cell
M. Rashidi, Asghar Asgari
In this paper, a novel lateral quantum well solar cell has been introduced, and the structural parameters effects of these nano-structures on the performance of the device have bee…
Time-Resolved Imaging of Negative Differential Resistance on the Atomic Scale
Mohammad Rashidi, Marco Taucer, Isil Ozfidan +6
Negative differential resistance remains an attractive but elusive functionality, so far only finding niche applications. Atom scale entities have shown promising properties, but v…
Multiple Silicon Atom Artificial Molecules
John A. Wood, Mohammad Rashidi, Mohammad Koleini +2
We present linear ensembles of dangling bond chains on a hydrogen terminated Si(100) surface, patterned in the closest spaced arrangement allowed by the surface lattice. Local dens…
Scanning tunneling spectroscopy reveals a silicon dangling bond charge state transition
Hatem Labidi, Marco Taucer, Mohammad Rashidi +6
We report the study of single dangling bonds (DB) on the hydrogen terminated silicon (100) surface using a low temperature scanning tunneling microscope (LT-STM). By investigating…
