In recent years, researchers have successfully produced an array of crystalline materials only one or a few atoms thick with nearly perfect structure....

Employing a combination of the many-body configuration-interaction method described by an extended Hubbard model and first-principles calculations, we predict the emergence of high...

We experimentally demonstrate a negative Kerr nonlinearity for quasiundoped graphene. Hereto, we introduce the method of chirped-pulse-pumped self-phase modulation and apply it to...

We report unusual physics associated with wave scattering in pseudospin-1 systems whose band structure consists of a conventional Dirac cone and a topologically...

One important attribute of graphene that makes it attractive for high-performance electronics is its inherently large thermal conductivity (κ) for the purposes of...

In this paper, we study the Schottky transport in a narrow-gap semiconductor and few-layer graphene in which the energy dispersions are highly nonparabolic....

If you bottle up a gas and try to image its atoms using today’s most powerful microscopes, you will see...

We report subnanometer, high-bandwidth measurements of the out-of-plane (vertical) motion of atoms in freestanding graphene using scanning tunneling microscopy. By tracking the vertical...

COVID-19 has impacted many institutions and organizations around the world, disrupting the progress of research. Through this difficult time APS and the Physical...

Zhang et al. reported a theoretical study of the optical spectra of monolayer graphene employing the Kubo formula within a tight-binding model. Their...

Quantum computers are largely hypothetical devices that could perform some calculations much more rapidly than conventional computers can. Instead of...
