van′ der Waals'` forc`es (ˈvæn dər ˌwɑlz, ˌwɑls) n.pl. weakly attractive forces that act between neutral atoms or molecules. [1925–30; after J. Dutch. van derWaals(1837–1923), Dutch physicist] Random House Kernerman Webster's College Dictionary, © 2010 K Dict...
It can be summarised by the following formula: (2.10)AH=π2Cρ1ρ2 where ρ1 and ρ2 are the number of atoms per unit volume in the two interacting materials. There are some general properties of van der Waals interactions between macroscopic bodies, which are worthy of note. First, ...
van der Waals force n. A weak, short-range attractive force between atoms or molecules caused by their dipole moments, often arising in otherwise nonpolar atoms or molecules from a temporary shift of orbital electrons to one side of one atom or molecule. ...
The L>0 phase shifts δL for low-energy scattering by a van der Waals r-6 potential are calculated using the two-potential formula of scattering theory. We calculate tanδL up to and including the k2L+5lnk term. We compare our results with those obtained using the Born approximation....
van der Waalsatom*-atom interactionsurface polaritonsurface enhancedUsing a recently obtained (general) formula for the interaction energy between an excited and a ground-state atom [Y. Sherkunov, Phys. Rev. A 75, 012705 (2007)], we consider the interaction energy between two such atoms near...
(for example, film thickness). Layered van der Waals (vdW) materials such as graphite and transition metal dichalcogenides (TMDs) provide an ideal material platform for designing such high-ρmaterials. They generally have excellent intrinsic in-plane thermal conductivities (κ||) in single-...

The magnetoelectric (ME) effect is a fundamental concept in modern condensed matter physics and represents the electrical control of magnetic polarisations or vice versa. Two-dimensional (2D) van-der-Waals (vdW) magnets have emerged as a new class of materials and exhibit novel ME effects with ...
Two-dimensional (2D) van der Waals heterostructures are promising for reducing the dark current and achieving high-performance room-temperature-operated mid-infrared photodetectors11,12,13,14,15,16,17. However, despite continued advancements, simultaneously achieving high sensitivity, fast response speed,...
