Abstract
The quantum Hall effect has been measured in an intrinsic semimetallic superlattice with almost equal electron and hole densities. Giant osc illations are seen in the Hall resistivity, and at high fields and pre ssures a zero-resistance state is observed where the Hall resistivity goes to zero due to compensation of the Hall fields of the two carrier types. This behaviour is interpreted in terms of the limiting propert ies of rho(xx) and rho(xy)
