Abstract

Graphene nanoribbons (GNRs) make up an extremely interesting class of
materials. On the one hand GNRs share many of the superlative properties of
graphene, while on the other hand they display an exceptional degree of tunability
of their optoelectronic properties. The presence or absence of correlated
low-dimensional magnetism, or of a widely tunable band gap, is determined by the
boundary conditions imposed by the width, crystallographic symmetry and edge
structure of the nanoribbons. In combination with additional controllable parameters
like the presence of heteroatoms, tailored strain, or the formation of
heterostructures, the possibilities to shape the electronic properties of GNRs
according to our needs are fantastic. However, to really benefit from that tunability
and harness the opportunities offered by GNRs, atomic precision is strictly required
in their synthesis. This can be achieved through an on-surface synthesis approach,
in which one lets appropriately designed precursor molecules to react in a selective
way that ends up forming GNRs. In this chapter we review the structure-property
relations inherent to GNRs, the synthesis approach and the ways in which the varied
properties of the resulting ribbons have been probed, finalizing with selected
examples of demonstrated GNR applications.

Abstract

During the past 10 years, two-dimensional materials have found incredible attention in the scientific community. The first two-dimensional material studied in detail was graphene, and many groups explored its potential for electronic applications. Meanwhile, researchers have extended their work to two-dimensional materials beyond graphene. At present, several hundred of these materials are known and part of them is considered to be useful for electronic applications. Rapid progress has been made in research concerning two-dimensional electronics, and a variety of transistors of different two-dimensional materials, including graphene, transition metal dichalcogenides, e.g., MoS2 and WS2, and phosphorene, have been reported. Other areas where two-dimensional materials are considered promising are sensors, transparent electrodes, or displays, to name just a few. This Special Issue of Electronics is devoted to all aspects of two-dimensional materials for electronic applications, including material preparation and analysis, device fabrication and characterization, device physics, modeling and simulation, and circuits. The devices of interest include, but are not limited to transistors (both field-effect transistors and alternative transistor concepts), sensors, optoelectronics devices, MEMS and NEMS, and displays.
