Abstract
A highly superlinear in radiation intensity photoconductance induced by continuous wave terahertz laser radiation with low intensities has been observed in quantum point contacts made of GaAs quantum wells operating in the deep tunneling regime. For very low values of the normalized dark conductance Gdark/G0≈10−6, with the conductance quantum G0=2e2/h, the photoconductance scales exponentially ...
