Large positive in-plane magnetoresistance induced by localized states at nanodomain boundaries in graphene

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-9 (2017)

Owing to long spin lifetime and diffusion length, graphene holds promise for spintronics, yet it does not possess intrinsic magnetic properties. Here, the authors observe experimentally a large, positive magnetoresistance at graphene nanodomain bound

Publikováno v: ACS nano

Renewed interest in the ferroelectric semi-conductor germanium telluride was recently triggered by the direct observation of a giant Rashba effect and a 30-year-old dream about a functional spin field-effect transistor. In this respect, all-electrica

Anomalous behavior of the electronic structure of ( Bi1−xInx)2Se3 across the quantum phase transition from topological to trivial insulator

Autor: Stefan Blügel, Lada V. Yashina, D. Y. Tsukanova, Gustav Bihlmayer, Oliver Rader, Andrei Varykhalov, Irene Aguilera, F. Freyse, E. D. L. Rienks, Carolien Callaert, Alexander N. Chaika, Joke Hadermann, Artem M. Abakumov, Jaime Sánchez-Barriga

Publikováno v: Physical Review B. 98

The authors investigate the electronic and spin structure of topological surface states across a topological quantum phase transition. They find a surface band gap opening at the Dirac point of the topological surface states, giving rise to massive f

A photochemical approach for a fast and self-limited covalent modification of surface supported graphene with photoactive dyes

Autor: Billy Richards, David P. Martin, Igor V. Shvets, Brian Walls, Victor Yu. Aristov, Alexander N. Chaika, O. V. Molodtsova, Sergey A. Krasnikov, Natalia N. Sergeeva, Barry E. Murphy, Karsten Fleischer, Gin Jose, Killian Walshe

Publikováno v: Nanotechnology. 29(27)

Herein, we report a simple method for a covalent modification of surface supported graphene with photoactive dyes. Graphene was fabricated on cubic-SiC/Si(001) wafers due to their low cost and suitability for mass-production of continuous graphene fi

Transport Gap Opening and High On–Off Current Ratio in Trilayer Graphene with Self-Aligned Nanodomain Boundaries

Publikováno v: ACS nano 9(9), 8967-8975 (2015). doi:10.1021/acsnano.5b02877

Trilayer graphene exhibits exceptional electronic properties that are of interest both for fundamental science and for technological applications. The ability to achieve a high on–off current ratio is the central question in this field. Here, we pr
