Data on Vacuum Technology Detailed by Researchers at Saha Institute of Nuclear Physics (Homoepitaxy of germanium by hyperthermal ion irradiation)

August 12, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Investigators publish new report on Vacuum Technology. According to news reporting originating from Kolkata, India, by VerticalNews correspondents, research stated, "A dense array of faceted nanostructures evolves on the Ge (001) surfaces for normal incidence hyperthermal ion bombardment at elevated temperatures."

Our news editors obtained a quote from the research from the Saha Institute of Nuclear Physics, "There is a narrow window of temperatures, just above the crystal annealing temperature, in which the grown pattern resembles to the checkerboard pattern of alternating mounds and pits as often observed under the conditions of molecular beam epitaxial growth process."

According to the news editors, the research concluded: "The measured roughness exponent characterizing the interface morphology is found to be extremely sensitive to substrate temperature and follows the dynamics of diffusion-bias-generated growth processes."
