Abstract

Epitaxial growth of thin CaSi2 films on various silicon surfaces is described. Transforming the silicide into siloxene leads to high quality epitaxial siloxene films with different orientations. The structural quality of CaSi2 and siloxene is investigated by transmission and scanning electron microscopy as well as X-ray diffraction analysis. Siloxene on (110)-Si enables direct observation of the anisotropic vibrational properties by IR transmission measurements. A diode structure was realized with siloxene by using contacts with different work functions as charge carrier injectors.
