“…For V dc = 0, these variations are small [11]; nevertheless, in such structures it is possible to achieve a value of β of the order of 10 A/W, which is only twice as low as for the Schottky diode [12]. The results weakly depend on the well thickness.…”

“…The result is determined by a number of phenomenological parameters (tunnel matrix elements and widths of size-quantized levels). The most stringent theory of the detection in the RTSs based on the use of the Floquet theorem for finding a steady-state solution of a nonstationary Schrodinger equation with a time-periodic electric field was developed in [11]. This approach is free from a limitation both on frequency ν and on amplitude V ac of the alternating field.…”

“…This approach is free from a limitation both on frequency ν and on amplitude V ac of the alternating field. The possibility was shown in [11] of a direct current resonant amplification in double-well structures at a signal frequency satisfying the condition ≈ -( and are the energies of size-quantized levels). In the asymmetric RTSs, the detection is possible in the absence of a DC bias, which makes it possible to create detectors without a bias (zero-biased detectors).…”

The phenomenon of terahertz radiation detection by resonant tunneling structures (RTSs) has been studied. The calculations of the changes ΔI 0 in the direct current (DC) component I 0 under the action of an alternating electric field were carried out by the solution of a nonstationary Schrodinger equation with a time-periodic electric field based on the Floquet mode expansion of the wave functions. The dependences of the DC component I 0 in resonant tunneling structures on the frequency ν and AC signal amplitude V ac have been built. It is shown that the ΔI 0 value in triple-barrier RTSs at resonance frequency ≈ -( and are the energies of the size-quantized levels) can exceed a low-frequency value by more than an order of magnitude. The parameters of the structures have been optmized, in order to use them in the terahertz radiation detectors in the anbsence of an external bias. The possibility of tuning the resonance frequency in the terahertz range by changing the DC bias has been shown.
