Insulator-metal transition in CaTiO3 quantum dots induced by ultrafast laser pulses |
[(a) and (b)] Highest electron level, [(c) and (d)] electron number across Fermi level (NF), [(e) and (f)] metallicity of two kinds of QDs varies with laser in 0 fs–9 fs, where [(a), (c), and (e)] and [(b), (d), and (f)] referring to PCTO and MCTO, respectively. |
