FIG. 1.

Time evolution of the relative number of hot electrons for NTs with , , , calculated for forward propagating electrons with energies over 50 keV (black solid line), 100 keV (red dashed line), and 500 keV (blue dotted line) for and . The results for a -thick planar target are also shown in black dot-dashed line, red dot-dot-dashed line, and blue short-dashed line, respectively.

FIG. 4.

Forward-electron energy spectra for (black solid line), 4.8 (red dashed line), 6.8 (magenta dot-dot-dashed line), and 11.78 (blue dot-dashed line) at , and , , , and . The numbers on the curves indicate their average slopes. Inset: the hot-electron temperature, or slope of , as a function of the laser strength (black solid curve with filled circles). The scaling laws for the hot-electron temperature according to the theories of Beg (red dashed line), ponderomotively driven electrons (blue dotted line), and Haines (magenta dot-dashed line) are also shown.
