The deposition of carbon is the key to yielding pit-free graphene terraces on SiC(0 0 0 1) surfaces. We present a novel technique to form a carbon overlayer at the monolayer scale on a SiC(0 0 0 1) Si-face substrate involving plasma oxidation at atmo

We demonstrate that pyramidal etch pits composed of (111) micro facets are formed on single-crystalline Ge(100) surfaces when the Ge samples with metallic particles are immersed into water. The mechanism behind this anisotropic etching is the enhance

We propose the metal-assisted chemical etching of Ge surfaces in water mediated by dissolved oxygen molecules (O2). First, we demonstrate that Ge surfaces around deposited metallic particles (Ag and Pt) are preferentially etched in water. When a Ge(1

The authors demonstrate that Ge(100) surfaces containing metallic particles are etched anisotropically in water. This originates from the catalytic reduction of dissolved oxygen (O2) in water to water molecules (H2O) on the metallic particles, which

The preparation of a silicon-carbide (SiC) surface composed of atomically flat terraces and single bilayer steps is essential for the epitaxial growth of high-quality graphene films. We develop a method to flatten a 4H-SiC(0001) surface on the atomic
