Using calculations on defective graphene from first principles, we herein consider the dependence of the properties of the monovacancy of graphene under isotropic strain, with a particular focus on spin moments. At zero strain, the vacancy shows a spin moment of 1.5 $\\mu_B$ that increases to...
Moreover, the frequency range of surface waves can also be controlled by increasing the number of graphene layers, as shown in Fig. 14C. The dependence of the frequency range in which surface waves exist on the thickness of dielectric and layer number of graphene sheets provides an ...
Recently, a mixture of graphene layers and plasmonic nanoparticles has been employed as an approach to enhance the photocurrent and responsivity of photodetectors (Kim et al., 2014; Koppens et al., 2011; Schackleford et al., 2009; Furchi et al., 2012; Freitag et al., 2013b). Graphene ...
Here we combine a range of computational approaches to enable a first-principles-level investigation of a single layer of water within a graphene-like channel. We find that monolayer water exhibits surprisingly rich and diverse phase behaviour that is highly sensitive to temperature and the van der...
or thinner samples is only seen with graphene encapsulation20,21,22. Our unprotected 1 u.c. BSCCO-2212 devices are superconducting and we do not find a direct correlation between thickness and mobility leading us to conclude that the degree of disorder is the important parameter. This result...
We investigate adiabatic quantum pumping through a normal-metal–"insulator"–superconductor (NIS) junction in a monolayer of graphene. The pumped current ... M Alos-Palop,M Blaauboer - 《Physical Review B Condensed Matter》 被引量: 13发表: 2011年 ...
The gap equation for Dirac quasiparticles in monolayer graphene in constant magnetic and pseudomagnetic fields, where the latter is due to strain, is studied in a low-energy effective model with contact interactions. Analyzing solutions of the gap equation, the phase diagram of the system in the...
A molecular-level picture of the structure and dynamics of nano-confined water is a prerequisite to understanding and controlling the behavior of water under confinement, with water-graphene interfaces being the most scientifically fascinating and technologically relevant systems. Here we explore a ...
Even though the integration of graphene into transistor results in excellent three terminal devices, the ratio of ION to IOFF is considerably low as compared to MOSFET. Although this is a major concern in the field of electronics, the graphene-based devices are still preferred to high electron ...
Such states are typically formed through phase transitions under non-equilibrium conditions and the final state is reached through processes that span a large range of timescales. Conventionally, phase diagrams of materials are thought of as static, without temporal evolution. However, many functional ...
