    We theoretically demonstrate that the exchange effect induced by the carrier-carrier interaction can cause the hybridization of the electron and hole dispersion relations in InAs/GaSb-based type II and broken-gap quantum well (QW) systems. As a result, a terahertz minigap at the anticrossing...
