Mani observed zero-registance states similar to those quantum-Hall-effect states in GaAs-AlGaAs but without the Hall resistance plateaus upon the application of radiations R. G. Mani, Physica E 22, 1 2004. An interpretation is presented. The applied radiation excites -holes-. The condensed composite c-bosons formed in the excited channel create a superconducting state with an energy gap. The supercondensate suppresses the non-condensed c-bosons at the higher energy, but it cannot suppress the c-fermions in the base channel, and the small normal current accompanied by the Hall field yeilds a B-linear Hall resistivity.
