At very low density, the electrons in a uniform electron gas spontaneously break symmetry and form a crystalline lattice called a Wigner crystal ... We clearly observe the emergence of the hexagonal ...

They are also deemed crucial as tiny logic elements in quantum computers that operate at cryogenic temperatures, and there is a need to elucidate the properties of superconductors at cryogenic ...

Scientists announce the discovery of slab waveguides based on the two-dimensional material hexagonal boron nitride. The U.S. Naval Research Laboratory (NRL), in collaboration with Kansas State ...

Abstract: A recently published rectangular unit cell based finite difference time domain (FDTD) method used to calculate the energy bands of perfect two-dimensional (2D) photonic crystals (PTCs) with ...

These findings question current theories and could fuel advancements in nanotechnology and quantum sensing. When some semiconductors absorb light, excitons (or particle pairs made of an electron bound ...

Two-dimensional quantum freeze Nanoparticles cooled to quantum ground-state in two motional dimensions. Date: March 6, 2023 Source: University of Innsbruck Summary: Researchers have succeeded in ...

Boron nitride nanosheets (BNNSs) were prepared as thermally conductive fillers using hexagonal boron nitride (h-BN) powder as raw material by a water exfoliation method. A composite film was prepared ...

In this paper, a hybrid topological material with hexagonal lattice ... the quantum Hall effect. In the simulation, the excitation source (denoted by a yellow star in Figure 4B) is set at the left ...

In this paper, several properties of two-dimensional photonic crystals composed of germanium are studied. We consider four cases i.e. hexagonal lattice of germanium rods in air, hexagonal lattice of ...

Heteroepitaxy of two-dimensional (2D) crystals, such as hexagonal boron nitride (BN) on graphene (G), can occur at the edge of an existing heterointerface. Understanding strain relaxation at such 2D ...
