Electron-Induced Formation of C on Si(100) from Acetylene and Ethylene
Oliver MacLean, Marc Savoie, Damian G. Allis +12
Hydrogen Desorption Lithography on Si(100) demonstrates the ability of the Scanning Tunneling Microscope (STM) to create functional atomic-scale structures and devices. The dehydro…
Towards Atom-by-Atom Fabrication: Mechanosynthetic donation and abstraction
Brandon Blue, Mathieu Morin, Alex Inayeh +55
Enabled by inverted-mode scanning tunneling microscopy (IM-STM) and the use of functionalized molecular tools, we demonstrate positionally-controlled mechanosynthetic addition (don…
Atomically precise mechanosynthesis of carbon structures on hydrogenated Si(100) by inverted-mode STM
Megan Cowie, Chris Deimert, Ryan Groome +44
The ability to build atomically precise structures on surfaces with complete control over both atomic placement and chemical bonding remains a central challenge in nanoscale fabric…
Inverted-Mode Scanning Tunneling Microscopy for Atomically Precise Fabrication
Eduardo Barrera, Bheeshmon Thanabalasingam, Rafik Addou +57
Scanning Tunneling Microscopy (STM) enables fabrication of atomically precise structures with unique properties and growing technological potential. However, reproducible manipulat…
Molecular Tools for Non-Planar Surface Chemistry
Taleana Huff, Brandon Blue, Terry McCallum +30
Scanning probe microscopy (SPM) investigations of on-surface chemistry on passivated silicon have only shown in-plane chemical reactions, and studies on bare silicon are limited in…
Design of a molecular Field Effect Transistor (mFET)
Ralph C. Merkle, Robert A. Freitas, Damian G. Allis
Field Effect Transistors (FETs) are ubiquitous in electronics. As we scale FETs to ever smaller sizes, it becomes natural to ask how small a practical FET might be. We propose and…
