Structures of clean and nickel-containing high Miller index surfaces of silicon

Macroscopic and nanoscale faceting of germanium surfaces

“…On the other hand, potential applications of high-index silicon surfaces in the semiconductor industry have been stimulating investigations of high-index silicon surfaces. 4,5 Although such investigations were started in the early 1980s, 6,7,8 they became hot only recently: [9][10][11][12][13][14][15][16][17][18][19][20] first, the most stable high-index surface Si͑113͒ ͑Refs. 10-14͒ and then others.…”

“…10-14͒ and then others. [15][16][17][18][19][20] Germanium surfaces, including both low-and high-index ones, have received much less attention than their silicon counterpart only because of their less importance in technological applications. 2,21 However, we believe that from a basic scientific point of view, investigations of germanium surfaces should not be neglected and that a comparison of germanium surfaces with their silicon counterpart can make our knowledge about group-IV semiconductor surfaces and interfaces more systematic and thus more comprehensive.…”

Magnetic Enhancement and Nitriding Process of Fe Atomic Layers on Si (111)-7×7-CH3OH Surface

“…The rectangular Si(111) substrate (n-type, ~ 0.1 Ω cm) of 1×7×0.3 mm 3 was ultrasonically pre-cleaned in acetone, ethanol and deionized water. In the preparation chamber, a clean well-ordered 7×7 reconstructed surface can be obtained after repeatedly ashed [22,23]. During the adsorption process of CH 3 OH (or NH ), the mass spectrometer was turned on to monitor the gaseous molecules composition in the observation chamber.…”
