Studies on SiC film deposited by pulsed XeCl excimer laser sputtering method

Physica B: Condensed Matter, 1996
Abstract Thin films of SiC were grown by pulsed excimer laser deposition (PLD). The quality and structure of the films were examined by AES, XPS, TEM, SEM, XRD and IR. The deposited films were dense and uniform and stuck tightly to the substrates. The compositions of the films were quite uniform and the ratio of silicon to carbon atomic in the films ...

Laser-pulse sputtering of atoms and molecules .2. Recondensation effects

1994
When solids are sputtered with sufficiently intense laser pulses, particle release takes place, and a terminating expansion then develops. The resulting gas-dynamic processes depend on whether backscattered particles are subject to recondensation or reflection. We here wish to examine the problem further with emphasis on-recondensation effects.

On the role of thermal processes in sputtering and composition changes due to ions or laser pulses

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1998
Abstract We here discuss some aspects of thermal processes due to ion-beam or laser-pulse interaction with solid surfaces. Considering first normal vaporization, i.e. particle emission in terms of the Hertz–Knudsen equation, we will show that it may have a limited importance with ions but has a very great importance with laser pulses.

Gas dynamics of the pulsed emission of a perfect gas with applications to laser sputtering and to nozzle expansion

Physical Review A, 1992
Particles released from a target surface by laser-pulse bombardment normally collide with each other and, as a result, exhibit three limiting categories of gas-dynamic behavior. One possibility, (a), is that the particles pass directly into unsteady adiabatic expansion (UAE), a problem for which an analytical solution already exists. Alternatively, (b),

Synthesis of GeSn alloys by sputter deposition and Pulsed Laser Melting

The realization of high Sn content Ge1-ySny alloys has been the center of numerous research studies over the last two decades. The reason for this lies in the fact that a Sn concentration higher than the solid solubility limit (1 at. %) lowers the Ge conduction band minima until reaching the crossover from indirect to direct bandgap.
