Moment-Fourier approach to ion parallel fluid closures and transport for a toroidally confined plasma
Jeong-Young Ji, Eric D. Held, J. Andrew Spencer +1
A general method of solving the drift kinetic equation is developed for an axisymmetric magnetic field. Expanding a distribution function in general moments a set of ordinary diffe…
Electron parallel closures for various ion charge numbers
Jeong-Young Ji, Sang-Kyeun Kim, Eric D. Held +1
Electron parallel closures for the ion charge number [J.-Y. Ji and E. D. Held, Phys. Plasmas \textbf{21}, 122116 (2014)] are extended for . Parameters are comput…
Ion parallel closures
Jeong-Young Ji, Hankyu Q. Lee, Eric D. Held
Ion parallel closures are obtained for arbitrary atomic weights and charge numbers. For arbitrary collisionality, the heat flow and viscosity are expressed as kernel-weighted integ…
Electron parallel closures for arbitrary collisionality
Jeong-Young Ji, Eric D. Held
Electron parallel closures for heat flow, viscosity, and friction force are expressed as kernel-weighted integrals of thermodynamic drives, the temperature gradient, relative elect…
Low temperature silicon epitaxy on hydrogen terminated Si(100) surfaces
Jeong-Young Ji, T. -C. Shen
Si deposition on H terminated Si(100)-2x1 and 3x1 surfaces at temperatures 300-530 K is studied by scanning tunneling microscopy. Hydrogen apparently hinders Si adatom diffusion an…
The role of antiphase boundaries during ion sputtering and solid phase epitaxy of Si(001)
J. C. Kim, J. -Y. Ji, J. S. Kline +2
The Si(001) surface morphology during ion sputtering at elevated temperatures and solid phase epitaxy following ion sputtering at room temperature has been investigated using scann…
