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…
Ultrafast Dynamics of the Topological Semimetal GdSbTe In the Presence and Absence of a Charge Density Wave
Robert J. Kirby, Angela Montanaro, Francesca Giusti +8
Time-resolved dynamics in charge-density-wave materials have revealed interesting out-of-equilibrium electronic responses. However these are typically only performed in a single ma…
Photoinduced Band Renormalization Effects in ZrSiS Topological Nodal-line Semimetal
Somnath Biswas, Ioannis Petrides, Robert J. Kirby +7
Out-of-equilibrium effects provide an elegant pathway to probing and understanding the underlying physics of topological materials. Creating exotic states of matter using ultrafast…
Signature of an Ultrafast Photo-Induced Lifshitz Transition in the Nodal-Line Semimetal ZrSiTe
Robert J. Kirby, Lukas Muechler, Sebastian Klemenz +6
Here we report an ultrafast optical spectroscopic study of the nodal-line semimetal ZrSiTe. Our measurements reveal that, converse to other compounds of the family, the sudden inje…
Weyl-fermions, Fermi-arcs, and minority-spin carriers in ferromagnetic CoS2
Niels B. M. Schröter, Iñigo Robredo, Sebastian Klemenz +15
The pyrite compound CoS2 has been intensively studied in the past due to its itinerant ferromagnetism and potential for half-metallicity, which make it a promising material for spi…
