Comment on “Sputtering transport theory: The mean energy”

Abstract

A method to calculate the sputtering yield energy distribution based on the ion energy dependence of total sputtering yields is given and is used to show that the "cutoff" yield energy distribution published in Physical Review B in 1988 ͓G. Falcone, Phys. Rev. B 38, 6398 ͑1988͔͒ is not tenable.

Modified Sigmund sputtering theory: isotopic puzzle

“…: +0554 6632650; Email: hnzhangbch@mail.ahbbptt.net.cn A realistic way to solve the isotopic puzzle is looking for an anisotropic correction of Sigmund isotropic theory [5,6]. Recently, for a single element target, we derived the ion energy dependence of the total sputtering yield and the angular and energy distributions of sputtered atoms induced by low energy and heavy ion bombardment [13,14] …”

Thickness dependence of two-dimensional photonic quasicrystal lens imaging characteristics

“…a micro-lens, due to the presence of various aberrations and size limitations. Researchers have found that two-dimensional (2D) photonic crystal (PC) lenses can break diffraction limits [1][2][3] and offer perfect non-near-field imaging [4] with structural modification; these lenses appear to be the micro-lens of choice in certain applications. Researchers further found that 2D photonic quasicrystal (PQC) lenses can provide far-field subwavelength imaging [5] and non-near-field focusing for unpolarized electromagnetic waves [6] without complex structural modifications, both experimentally and theoretically.…”

Subsurface energy systems in China: production, storage and conversion

“…Luo et al (2015a) provide a fundamental study on stability evaluation of the underground gas storage in rock salts based on new partitions of the surrounding rock. They found that more scientific studies (including the international expertise) are necessary to proceed with renewable energy topics (RET) particularly in China (Zhang 2005). Results to date suggest that adequate reconciliation cannot be achieved using calculated mixing energies only, and the authors propose the use of shear rate instead.…”
