## Description

- description: We demonstrate a quantum ratchet detector, which is a high-resistance
    photovoltaic mid-infrared detector based on an engineered spatial arrangement
    of subbands. In photovoltaic quantum-well photodetectors, in which unidirectional
    photocurrent is generated by asymmetric quantum-well structures, maximization
    of device resistance by suppressing undesired electron transports is crucial for
    minimizing noise. A semi-quantitative guideline suggests the significance of spatial
    separation between wavefunctions for reducing the conductance from the ground
    state. Here, we employ a step quantum well made of a shallow floor and a deep
    well. Photoexcited electrons are quickly transferred to a separated location from
    the ground state through fast resonant tunneling and phonon scattering, and then
    they are allowed to flow in only one direction. This architecture is made possible
    by the use of a GaAs/AlGaAs material system, and it achieves a resistance as high
    as 6.0×104 Ωcm2 with a single-period structure. Combined with optical patch antennas
    for responsivity enhancement, we demonstrate a maximum background-limited specific
    detectivity of 6.8×1010 cmHz1/2/W at 6.4 μm, 77 K for normal incidence, and a
    background-limited-infrared-photodetector temperature of 98 K.
