| 内容記述 | We investigate the initial phase of Bloch oscillations in a GaAs-based superlattice designed for fine bias control of interminiband mixing. The type of oscillation current, determined from terahertz emission with the time origin (t = 0), is found to shift gradually from damped cos ω B t to damped sin ω B t (ω B / 2 π: Bloch frequency) as the dc bias electric field is increased. This demonstrates a continuous transition between the capacitive and conductive responses, which have been previously reported in the two regimes where electron wavefunctions are Wannier–Stark localized within a nearly isolated miniband and delocalized by substantial interminiband mixing, respectively. | |||||||||||||||
