Topologically enhanced optical helicity density in the thermal near field of twisted bilayer van der Waals materials
Xiaohong Zhang, Chiyu Yang, Wenshan Cai +1
Twisted van der Waals (vdW) bilayers can support tunable surface/hyperbolic phonon polariton (S/HPhP) depending on the interlayer twist angle. S/HPhPs can be thermally excited and…

A van der Waals material exhibiting room temperature broken inversion symmetry with ferroelectricity
Fabia F. Athena, Cooper A. Voigt, Mengkun Tian +8
Since the initial synthesis of van der Waals two-dimensional indium selenide was first documented in 1957, five distinct polymorphs and their corresponding polytypes have been iden…
