title: Molybdenum diselenide: rhombohedral high pressure-high temperature polymorph.
abstract: A three-layered rhombohedral form of molybdenum diselenide has been produced by subjecting the normal two-layered hexagonal form to pressures of 40 kilobars and temperatures of 1500 degrees C. The new form is isostructural with rhombohedral molybdenum disulfide.
