Charged particle energy loss to electron gas

Abstract: The contribution of the conduction electrons to the stopping power (-dE/dx) of fast charged particles in a crystal has been calculated using different forms of the dielectric function. The various approximate forms of dielectic functions used are: 1, random phase approximation (RPA), 2. Hnbbard approximation (both, screened and unscreened), 3. Kleinman approximation, and 4. the dielectric function obtained by variational calculation of Langreth. The intermediate velocity range forthe incident particles, namely… Show more

“…(16a)), Echenique and co-workers [7] reported a reduction by $20% of hot-electron lifetimes (and thus IMFP) for energies a few eV above the Fermi level, in good agreement with our low-energy estimates. Also, in a comprehensive study on the effect of LFCs upon the electron-gas stopping-power, Pathak and Yussouff [56] found a small effect (few %) which agrees with our conclusions above 100 eV. On the other hand, Penn [57] found that in the 0.2-2 keV electron range the LFC leads to an increase of the IMFP by 10-20%.…”

“…2 for various values of the parameter, a, along with the values obtained by Pathak and Yussouff [2]. As expected, the values of stopping power depend upon the parameter, a, and we find that for a = 1.3 our values agree closely with the values obtained by Pathak and Yussouff [2]. It may also be noted that the energy dependence of stopping power obtained by Pathak and Yussouff is slightly different.…”

“…Cheshire et a1.53 followed the procedure of Clementi and Raimondi54 to obtain the Slater orbitals as cj, = ~~~y -~ exp( -5,r) YzEln, (8,4), (28) and above and applied to channeling situations is about the same. We note that the positions of maxima and minima are nicely predicted at about the correct values of Z1.…”
