Concise programme description

Objectives
The focus of the programme is the investigation and control of Dirac electrons in graphene, with two specific objectives in mind. Firstly, we aim at establishing a physical understanding of the fundamental processes of Dirac electrons in graphene through a close interplay between theoretical and experimental investigations. Secondly, we aim at the realization of electronic devices with potential for practical use, through the identification of new concepts and their implementation in proof-of-principle prototypes.

Background, relevance and implementation
Our understanding of electron transport in two dimensions relies on past investigations of two-dimensional electron gases (2DEGs) hosted in conventional semiconducting hetero­structures, where the quantum electron dynamics is governed by the Schrödinger equation. In graphene the electron dynamics is governed by the Dirac equation, which results in the occur­rence of new phenomena that defy our intuition. Examples of predicted manifestations of the Dirac nature of electrons in graphene include unusual size quantization, tunable magnetism, electrostatically controlled band-structure, etc. Also phenomena that are well understood in conventional 2DEGs –e.g., quantum interference, the quantum Hall effect, and the density dependence of the conductivity– exhibit striking and unexpected differences in graphene.
There is a wide consensus that the potential of graphene for integrated electronics should be explored in detail, and research in this area has been funded by leading integrated electronics manufacturers (e.g., Intel Corporation in the US and Samsung in South Korea). Our programme will address different aspects of applied electronics through the realization of prototype devices (for example field effect transistors, but also graphene qubits and spin valve devices) and through the develop­ment of new routes for material control.
The objectives pose many scientific and technological challenges that we will address by working on three key areas: elementary electronic processes in graphene, new graphene nanostructures, and graphene devices for applied electronics. In all key areas a close interplay between theory, experiments, and material development is needed and planned. Also the fundamental and applied objectives of the programme are closely interrelated: basic under­standing is needed to identify the optimal strategy for the realization and configuration of practical graphene devices, which, in turn, are crucial for fundamental investigation of graphene.

Remarks
The Dutch part of the EUROCORES EuroGRAPHENE project 'ENTangled Spin pairs in graphene' is administrated within this FOM programme.
