Van der Waals xenotaxy: Oriented growth of hexagonal GaSe ...

+

The growth of the layered chalcogenide GaSe on cleaved GaAs(110) surfaces was investigated with photoemission and lowenergy electron diffraction (LEED). GaSe films grow with their c axis perpendicular to the GaAs(110) surface. LEED patterns after initial film growth are a superposition of rectangular GaAs:Se spots and two hexagonal domains rotated by ±5° with respect to the GaAs …
