Calculation of time-dependent flows of sputtered material in the asymmetric alternating current glow discharge
Vacuum. 2007. Vol. 81. No. 6. P. 771-773.
Diffusion transport of material sputtered from the surface of the powered electrode in the asymmetric alternating current discharge is theoretically studied. It is shown that amplitudes of the non-stationary component of the sputtered atom (SA) flow densities at the electrodes depend on the discharge frequency and two dimensionless parameters, which are functions of the SA mass, its mean free path length in the background gas and the distance between the electrodes. It is found that diffusion damping of the time-varying component of the SA number density takes place in the discharge volume under certain conditions and their flows at the electrodes can be considered as time-independent.

A two-dimensional model of a sintered electrode activator (in particular, barium) transport in the arc discharge lamp tube volume, based on numerical solution of the non-stationary diffusion equation, is developed. The dependence of the barium atoms flow density at the electrode rod tip on fill gas pressure and electrode dimensions is investigated. It is found ...

We report the realization of STM-based lithography with silicon layers removal on the chlorinated Si(100)-2x1 surface at 77K. In contrast to other STM lithography studies, we were able to remove locally both chlorine and silicon atoms. Most of the etched pits have a lateral size of 10-20A and a depth of 1-5A. In the pits in ...

Hydrogen can be inserted into Si(100)-2 × 1-H during surface preparation or during the hydrogen desorption lithography used to create atomic-scale devices. Here, a hydrogen atom inserted into a hydrogen monolayer on the Si(100)-2 × 1 surface has been studied using density functional theory. Hydrogen-induced defects were considered in their neutral, negative, and positive charge ...

We insert and manipulate a single chlorine atom in chlorine monolayer on a Si(100)-2 × 1 surface using a scanning tunneling microscope. Two objects were created—a Cl atom in a groove between two dimer rows, and bridge-bonded Cl on a silicon dimer. Changing the voltage polarity leads to conversion of the objects into each other. ...

Halogen monolayer on a silicon surface is attracting active attention for applications in electronic device fabrication with individual impurities. To create a halogen mask for the impurities incorporation, it is desirable to be able to remove a single halogen atom from the surface.

Despite the interest in a chlorine monolayer on Si(100) as an alternative to hydrogen resist for atomic-precision doping, little is known about its interaction with dopant-containing molecules. We used the density functional theory to evaluate whether a chlorine monolayer on Si(100) is suitable as a resist for PH3, PCl3, and BCl3 molecules. We calculated reaction ...

Recently a theoretical scheme explaining the vorticity generation by surface waves in liquids was developed [Phys. Rev. Lett.116,054501(2016)]. Here we study how a thin (monomolecular) film presented on the surface of liquid affects the generated vorticity. We demonstrate that the vorticity becomes parametrically larger than for the case of liquid with a free surface, and ...
