Electrically-tunable ultra-flat bands and -electron magnetism in graphene nanoribbons
Ruize Ma, Nikita V. Tepliakov, Arash A. Mostofi +1
Atomically thin crystals hosting flat electronic bands have been recently identified as a rich playground for exploring and engineering strongly correlated phases. Yet, their varie…
One-dimensional magnetic conduction channels across zigzag graphene nanoribbon/hexagonal boron nitride heterojunctions
Michele Pizzochero, Nikita V. Tepliakov, Johannes Lischner +2
We examine the electronic structure of recently fabricated in-plane heterojunctions of zigzag graphene nanoribbons embedded in hexagonal boron nitride. We focus on hitherto unexplo…
Dirac half-semimetallicity and antiferromagnetism in graphene nanoribbon/hexagonal boron nitride heterojunctions
Nikita V. Tepliakov, Ruize Ma, Johannes Lischner +3
Half-metals have been envisioned as active components in spintronic devices by virtue of their completely spin-polarized electrical currents. Actual materials hosting half-metallic…
Unveiling and Manipulating Hidden Symmetries in Graphene Nanoribbons
Nikita V. Tepliakov, Johannes Lischner, Efthimios Kaxiras +2
Armchair graphene nanoribbons are a highly promising class of semiconductors for all-carbon nanocircuitry. Here, we present a new perspective on their electronic structure from sim…
Electrically Induced Dirac Fermions in Graphene Nanoribbons
Michele Pizzochero, Nikita V. Tepliakov, Arash A. Mostofi +1
Graphene nanoribbons are widely regarded as promising building blocks for next-generation carbon-based devices. A critical issue to their prospective applications is whether and to…
Crystal Field Effect and Electric Field Screening in Multilayer Graphene with and without Twist
Nikita V. Tepliakov, QuanSheng Wu, Oleg V. Yazyev
We address the intrinsic polarisation and screening of external electric field in a broad range of ordered and twisted configurations of multilayer graphene, using an ab initio app…
Exciton g-factors in monolayer and bilayer WSe from experiment and theory
J. Förste, N. V. Tepliakov, S. Yu. Kruchinin +7
The optical properties of monolayer and bilayer transition metal dichalcogenide semiconductors are governed by excitons in different spin and valley configurations, providing versa…
Enrichment of the Superheavy Element Rg in Natural Au
A. Marinov, A. Pape, D. Kolb +5
Based on the observation of the long-lived isotopes 261Rg and 265Rg (Z = 111, t(1/2) >= 10^(8) y) in natural Au, an experiment was performed to enrich Rg in 99.999% Au. 16 mg of Au…
