Researchers achieve charge-order-enhanced capacitance in semiconductor moiré superlattices
In recent years, electronics engineers have been experimenting with new materials that could be used to study electronic correlation phenomena. Van der Waals (vdW) moiré materials are particularly promising for examining these phenomena. VdW materials are composed of...
Researchers observe two-fold symmetric superconductivity in 2D niobium diselenide
In recent years, many material scientists worldwide have been investigating the potential of two-dimensional (2D) materials, which are composed of a single layer or a few ultrathin layers of atoms and have unique physical, electrical and optical properties.
Bound-charge engineering: A new strategy to develop nanowire transistors
In recent years, physicists and electronic engineers have been trying to identify materials that could be used to fabricate new types of electronic devices. One-dimensional (1-D) and two-dimensional (2-D) materials have been found to have particularly advantageous...
