The quantum spin Hall state is a state of matter in two-dimensional semiconductors that have a quantized spin-Hall conductance and a vanishing charge-Hall conductance. The quantum spin Hall state of matter is the cousin of the integer quantum Hall state, and does not require the application of a large magnetic field.
