Engineering Quantum Wire States for Atom Scale Circuitry
Max Yuan, Lucian Livadaru, Roshan Achal +3
Recent advances in hydrogen lithography on silicon surfaces now enable the fabrication of complex and error-free atom-scale circuitry. The structure of atomic wires, the most basic…
Structural Control of Atomic Silicon Wires
Furkan M. Altincicek, Christopher C. Leon, Lucian Livadaru +5
Bare Si(100)-21 surface atoms exhibit a buckled structure where one Si atom in a dimer is lowered while the other is raised, leading to two possible buckling configurations…
Electronic Structures of Atomic Silicon Dimer Wires as a Function of Length
Furkan M. Altincicek, Lucian Livadaru, Christopher C. Leon +6
Bare silicon dimers on hydrogen-terminated Si(100) have two dangling bonds. These are atomically localized regions of high state density near to and within the bulk silicon band ga…
Detecting and Directing Single Molecule Binding Events on H-Si(100) with Application to Ultra-dense Data Storage
Roshan Achal, Mohammad Rashidi, Jeremiah Croshaw +2
Many new material systems are being explored to enable smaller, more capable and energy efficient devices. These bottom up approaches for atomic and molecular electronics, quantum…
Electrostatic Landscape of a H-Silicon Surface Probed by a Moveable Quantum Dot
Taleana Huff, Thomas Dienel, Mohammad Rashidi +4
With nanoelectronics reaching the limit of atom-sized devices, it has become critical to examine how irregularities in the local environment can affect device functionality. Here,…
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…
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…
Binary Atomic Silicon Logic
Taleana Huff, Hatem Labidi, Mohammad Rashidi +5
It has long been anticipated that the ultimate in miniature circuitry will be crafted of single atoms. Despite many advances made in scanned probe microscopy studies of molecules a…
Single Electron Dynamics of an Atomic Silicon Quantum Dot on the H-Si(100) 2x1 Surface
Marco Taucer, Lucian Livadaru, Paul G. Piva +4
Here we report the direct observation of single electron charging of a single atomic Dangling Bond (DB) on the H-Si(100) 2x1 surface. The tip of a scanning tunneling microscope is…
Tomography of a High-Purity Narrowband Photon From a Transient Atomic Collective Excitation
A. MacRae, T. Brannan, A. I. Lvovsky
We demonstrate the efficient heralded generation of high purity narrow-bandwidth single photons from a transient collective spin excitation in a hot atomic vapour cell. Employing o…
