A semiconductor material that is only a few atoms thick, existing in two dimensions. These materials exhibit unique electronic and optical properties different from their bulk counterparts, making them suitable for advanced electronics and optoelectronics. Examples include graphene and molybdenum disulfide.
In semiconductor physics, a 'hole' is a quasiparticle representing the absence of an electron in an atom's valence band. It carries a positive charge and behaves like a positive charge carrier, moving through the crystal lattice. Hole conduction is a fundamental mechanism in p-type semiconductors.
Nature is a highly prestigious British multidisciplinary scientific journal, first published on November 4, 1869. It is one of the world's most cited and recognized academic journals, publishing original research across a wide range of scientific fields, including physical sciences, life sciences, and earth sciences.
