We study the superlattice minibands of the well-aligned bilayer-raphene/hexagonal-boronnitride heterostructure. In contrast to the monolayer-graphene/hexagonal-boron-nitride heterostructure, these are affected by the interlayer asymmetry of BLG-hBN heterostructure and trigonal warping....
Van der Waals encapsulation of two-dimensional materials in hexagonal boron nitride (hBN) stacks is a promising way to create ultrahigh-performance electronic devices1–4. However, contemporary approaches for achieving van der Waals encapsulation, which
Polaritons are confined hybrid light-matter excitations holding potential for optoelectronic and sensing applications, but their characterization is usually limited to optical spectroscopy. Here, the authors report the electrical spectroscopy of mid-infrared plasmon-phonon polaritons in Au/hBN/graphene nanoreso...
“Previous studies have neither considered all these intermediates nor such a large parameter space (temperature and particle density). We believe that it will be useful to guide chemical vapor deposition growth of hBN on other metallic substrates, as well as the synthesis of nanoporous or functiona...
We here show that for substrates made of the piezoelectric hexagonal boron nitride (hBN), in comparison to the widely used SiO2, this mechanism of remote phonon scattering is—at room temperature—weaker by almost an order of magnitude, and causes a resistivity of approximately 3 Ω. This ...

a Optical microscope image of a representative graphene spintronic device (D3) on SiO2 substrate. Vertical blue strip is the hBN-encapsulated graphene channel, pale yellow bars are ferromagnetic cobalt (Co) electrodes and bright yellow bars are gold (Cr/Au) reference contacts. Wc is contact width...
We have developed a dry transfer method that allows graphene to be transferred from polymer- thyl-methacrylate (PMMA)/Si (silicon) substrates on commercially available hexagonal boron ni- tride (hBN) crystals. With this method we are able to fabricate graphene devices with little wrin- kles ...
I will focus on the capture of small compact objects by supermassive black holes. With these captures we will test gravity in the strong regime, because they allow us to do relativistic geodesy - They are unique event horizon probes. 6R...
The influence of the optic axis orientation of hexagonal boron nitride (hBN) on thenear-field radiative heat transfer between hBN slabs as well as between graphene/hBN hetero-structures is studied. A modified4×4transfer matrix method is employed to calculate the near-field radiative heat flux (...
