Thin-layer black phosphorus/GaAs heterojunction p-n diodes

TL;DR: In this article, the p-n heterojunction diodes with thin black phosphorus layers are interfaced with an underlying, highly n-doped GaAs substrate, and the observed maximum open circuit voltage of 0.6 V is consistent with the band gap estimated for a black phosphorus sheet with a thickness on the order of 10nm.
Journal ArticleDOI

High Performance Graphene–Oxide–Metal Diode through Bias-Induced Barrier Height Modulation

TL;DR: In this paper, the authors present a Web of Science Record created on 2016-11-21, modified on 2017-05-12.Reference EPFL-ARTICLE-223319
Journal ArticleDOI

Chemical modification of graphene via hyperthermal molecular reaction.

TL;DR: This facile approach for the controlled modification of graphene extends the scope of candidate species that would not otherwise react via existing conventional methods.
Journal ArticleDOI

Self-assembly of a catechol-based macrocycle at the liquid–solid interface: experiments and molecular dynamics simulations

TL;DR: This combined experimental (STM, XPS) and molecular dynamics simulation study highlights the complex and subtle interplay of solvent effects and surface interactions on the 2-D self-assembly pattern of a Schiff-base macrocycle containing catechol moieties at the liquid-solid interface.
Journal ArticleDOI

Electric-field control of single-molecule tautomerization

TL;DR: By combining a graphene field-effect transistor and a gate-tunable scanning tunneling microscope (STM), this strategy enables the intramolecular H atom transfer of a metal-free macrocycle to be controlled with an external field.
