Resonant field emission from noble-metal/graphene heterostructures
Maxim Trushin
Field emission from metals underpinned early vacuum-tube technology, and recent nanoscale engineering made field-emission devices compatible with modern silicon platforms. However,…
Interlayer excitonic insulator in two-dimensional double-layer semiconductor junctions: An explicitly solvable model

Excitonic insulators conduct neither electrons nor holes but bound electron-hole pairs, excitons. Unfortunately, it is not possible to inject and detect the electron and hole curre…
Phonon-assisted carrier cooling in h-BN/graphene van der Waals heterostructures
Sangkha Borah, Dinesh Yadav, Maxim Trushin +1
Being used in optoelectronic devices as ultra-thin conductor-insulator junctions, detailed investigations are needed about how exactly h-BN and graphene hybridize. Here, we present…

Aleksandr Rodin, Maxim Trushin, Alexandra Carvalho +1
Research on 2D materials has been one of the fastest-growing fields in condensed matter physics and materials science in the past 10 years. The low dimensionality and strong correl…
Harnessing Exciton-Exciton Annihilation in Two-Dimensional Semiconductors

Electrons commonly couple through Fröhlich interactions with longitudinal optical phonons to form polarons. However, trions possess a finite angular momentum and should therefore c…
