It is concluded that it is valid to use a Boltzmann relation n(e) = n(e0)exp(eV/kT) for the electrons of density n(e), where the temperature T is approximately the electron temperature T-e, and that the density n(n) of the negative ions at low pressures obeys n(n) = n(n0)...
where q denotes the magnitude of the electrical charge on the electron, with a value 1.602 176 487(40) ×10−19 C and k is the Boltzmann constant in Joules/K. The Boltzmann constant can be expressed in electron volts as 8.617 343(15) ×10−5 eV/K, aiding easy calculation...

What is polarization in quantum physics? What are the first and second laws of thermodynamics? What is the probability of occupancy for a state whose energy is (i) 0.1 eV above the energy, (ii) 0.1 eV below the Fermi energy and (iii) equal to the Fermi energy? Assume a temperature of...
In a plasma model, the electron energy distribution function as well as the transport properties of the electrons (e.g., electron mobility) are needed. For the simplest cases, a Maxwellian EEDF and a constant value for the electron mobility can be used. The other transport properties are th...
The influence of the gravitational force on the droplet shape is also examined through the variations of the Bond number, where the droplet shape migrates from spherical to flattened interface in tandem with the increase of the Bond number. The predicted interfaces under constant Bond number are ...
and the spectra were detected with a step of 25 K in the range of 303–573 K. Especially, we set the heating rate of the temperature controller to 12.5 K min−1and kept the constant temperature for 12 min to ensure that the temperature of sample always reached the scheduled temperature...
