Controlled Synthesis of Organic/Inorganic van der Waals Solid for Tunable Light-Matter Interactions

Tutorial 3: van der Waals Interactions

Van der Waals interactions with soft interfaces

Many naturally occurring microbiological and synthetic polymer systems have soft interfaces due, e.g., to the presence of polymer brushes at the surfaces. The initial interactions (before contact) in such systems are typically physical rather than chemical in origin, e.g. electrostatic or van der Waals forces. We calculate the form of the summed van der Waals interaction energies UHS and USS be...

van der Waals interactions across stratified media.

Working at the Lifshitz level, we investigate the van der Waals interactions across a series of layers with a periodic motif. We derive the complete form of the van der Waals interaction as an explicit function of the number of periodic layers. We then compare our result with an approximation based on an anisotropic-continuum representation of the stratified medium. Satisfactory agreement betwe...

Tunable Electronic Properties in van der Waals Heterostructure Germanene/Germanane

It is challenging to epitaxially grow germanene on conventional semiconductor substrate. Based on first-principles calculations, we investigate the structural and electronic properties of germanene/germanane heterostructure (HTS). The results indicate that the Dirac cone with nearly linear band dispersion of germanene maintains in the band gap of substrate. Remarkably, the band gap opened in th...
