We study the variation of sputtering yields with surface morphologies under the assumption of a specially prescribed surface shape. Compared with a flat surface, we show that surface morphology can cause a decrease in the sputtering yield and an increase in the incident angle where sputtering yield is maximum. Based on Sigmund’s theory, an analytical formula for the morphology dependent sputter...
We report the growth and properties of a-axis oriented GdBa,CusO,-a high T, thin films on (100) SrTi03 substrates by dc magnetron sputtering. It is found that GdBa,Cu,O,-s films on (100) SrTiO, exhibit a-oriented growth at higher substrate temperatures compared with YBaQtsO,-& films. By utilizing low-temperature-grown u-axis GdBazCu,O,_.s films (200 A in thickness) as a self-template, pure a-ax...
It is widely accepted that Mars had an atmosphere at least 4 Gyr ago. The processes that led to the loss of the Martian atmosphere are still debated. Solar-wind-induced sputtering, impact erosion, weathering, sequestration into the regolith and polar caps, and photodissociative reactions are the mechanisms believed to be responsible for removing the atmosphere. No one process has been shown to ...
Anatase TiO2 thin films were deposited in a d.c. reactive magnetron sputtering system. It was found that there is a strong dependence between anatase-rutil structures of TiO2 films and the technological conditions, the most relevant parameter being the oxygen percentage from the argon and oxygen mixture. Our measurements carried out for electrical properties of d.c. magnetron sputtering TiO2 th...
