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…
Ionic Charge Distributions in Silicon Atomic Wires
Jeremiah Croshaw, Taleana Huff, Mohamad Rashidi +4
Using a non-contact atomic force microscope (nc-AFM), we examine continuous DB wire structures on the hydrogen-terminated silicon (100) 2x1 surface. By probing the DB structures at…
