2D van der Waals materials have rich and unique functional properties, but many are susceptible to corrosion under ambient conditions. Here we show that linear alkylamines are highly effective in protecting the optoelectronic properties of these materials such as black phosphorous (BP) and transitional metal dichalcogenides. As a representative example, n-hexylamine can be applied in the form of thin molecular monolayers on BP flakes with less-than-2nm thickness and can prolong BP's lifetime…

Creating a Stable Oxide at the Surface of Black Phosphorus.
Results indicate minimal charge transfer, suggesting that the oxide layer of in situ cleaved black phosphorus crystals is suitable for passivation or as an interface layer for further dielectric deposition.
Revealing Defect-State Photoluminescence in Monolayer WS2 by Cryogenic Laser Processing.
Cryogenic photoluminescence spectroscopy is shown to be a highly sensitive technique to the detection of oxidation induced degradation of monolayer tungsten disulfide (WS2) caused by exposure to ambient conditions.
Origin of photoresponse in black phosphorus phototransistors
We study the origin of a photocurrent generated in doped multilayer black phosphorus (BP) phototransistors, and find that it is dominated by thermally driven thermoelectric and bolometric processes.
Polarization-sensitive broadband photodetector using a black phosphorus vertical p-n junction.
A broadband photodetector using a layered black phosphorus transistor that is polarization-sensitive over a bandwidth from ∼400 nm to 3,750‽nm is demonstrated and might provide new functionalities in novel optical and optoelectronic device applications.
Computerised Measurement of Contact Angles
The measurement of the contact angle formed by a droplet of liquid placed on a horizontal surface – the so-called sessile drop – has been of interest to scientists and others for at least 200 years,
A consistent and accurate ab initio parametrization of density functional dispersion correction (DFT-D) for the 94 elements H-Pu.
The revised DFT-D method is proposed as a general tool for the computation of the dispersion energy in molecules and solids of any kind with DFT and related (low-cost) electronic structure methods for large systems.
Generalized Gradient Approximation Made Simple.
A simple derivation of a simple GGA is presented, in which all parameters (other than those in LSD) are fundamental constants, and only general features of the detailed construction underlying the Perdew-Wang 1991 (PW91) GGA are invoked.
Efficient iterative schemes for ab initio total-energy calculations using a plane-wave basis set.
An efficient scheme for calculating the Kohn-Sham ground state of metallic systems using pseudopotentials and a plane-wave basis set is presented and the application of Pulay's DIIS method to the iterative diagonalization of large matrices will be discussed.
Accurate and efficient algorithm for Bader charge integration.
We propose an efficient, accurate method to integrate the basins of attraction of a smooth function defined on a general discrete grid and apply it to the Bader charge partitioning for the electron
Special points for Brillouin-zone integrations
The efficiency of two different methods for obtaining "special" points useful for Brillouin-zone integrations of periodic functions is compared. We find that for some Bravais lattices (such as
