Interestingly, topological phase transitions from ferrovalley, half-valley metal to quantum anomalous Hall effect state appear with the increase of strain in VGe2N4 monolayer. More interestingly, half-metal state of valley induced by electronic correlation or strain can occur in VGe2N4 monolayer, which means 100% spin-polarized valley …The quantum Hall effect (or integer quantum Hall effect) is a quantized version of the Hall effect which is observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields, in which the Hall resistance Rxy exhibits steps that take on the quantized values. where VHall is the Hall voltage, Ichannel is the ...Fractional Quantum Hall Effect (FQHE) is a typical strong-correlated system.
