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…
A far-ultraviolet-driven photoevaporation flow observed in a protoplanetary disk
Olivier Berné, Emilie Habart, Els Peeters +143
Most low-mass stars form in stellar clusters that also contain massive stars, which are sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiati…
PDRs4All III: JWST's NIR spectroscopic view of the Orion Bar
Els Peeters, Emilie Habart, Olivier Berne +135
(Abridged) We investigate the impact of radiative feedback from massive stars on their natal cloud and focus on the transition from the HII region to the atomic PDR (crossing the i…
PDRs4All IV. An embarrassment of riches: Aromatic infrared bands in the Orion Bar
Ryan Chown, Ameek Sidhu, Els Peeters +136
(Abridged) Mid-infrared observations of photodissociation regions (PDRs) are dominated by strong emission features called aromatic infrared bands (AIBs). The most prominent AIBs ar…
PDRs4All II: JWST's NIR and MIR imaging view of the Orion Nebula
Emilie Habart, Els Peeters, Olivier Berné +139
The JWST has captured the most detailed and sharpest infrared images ever taken of the inner region of the Orion Nebula, the nearest massive star formation region, and a prototypic…
PDRs4All: A JWST Early Release Science Program on radiative feedback from massive stars
Olivier Berné, Émilie Habart, Els Peeters +134
Massive stars disrupt their natal molecular cloud material through radiative and mechanical feedback processes. These processes have profound effects on the evolution of interstell…
