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…
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…
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…
