Carbon is one of the most intriguing elements in the Periodic Table. It forms many allotropes,
some known from ancient times (diamond and graphite) and some discovered 10-20 years …

The scaling of silicon metal–oxide–semiconductor field-effect transistors has followed
Moore's law for decades, but the physical thinning of silicon at sub-ten-nanometre …

Two-dimensional semiconductors can be used to build next-generation electronic devices
with ultrascaled channel lengths. However, semiconductors need to be integrated with high …

As the Si-based transistors scale down to atomic dimensions, the basic principle of current
electronics, which heavily relies on the tunable charge degree of freedom, faces increasing …

We perform systematic investigations of transport through graphene on hexagonal boron
nitride (hBN) substrates, together with confocal Raman measurements and a targeted …

The ground state of charge-neutral graphene under perpendicular magnetic field was
predicted to be a quantum Hall topological insulator with a ferromagnetic order and spin …

We report on a scanning confocal Raman spectroscopy study investigating the strain-
uniformity and the overall strain and doping of high-quality chemical vapour deposited …

The spin-helical Dirac fermion topological surface states in a topological insulator nanowire
or nanoribbon promise novel topological devices and exotic physics such as Majorana …

Disorder‐induced magnetoresistance (MR) effect is quadratic at low perpendicular magnetic
fields and linear at high fields. This effect is technologically appealing, especially in 2D …

It is widely believed that carrier-density inhomogeneities (“electron-hole puddles”) in single-
layer graphene on a substrate such as quartz are due to charged impurities located close to …
