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…
