摘要：
A high band-gap material surrounded by two short-period superlattices of lower band gap is proposed for carrier confinement to the barrier. The combined structure behaves as a Fabry-Perot cavity for carriers as long as coherence of the carrier wave function is maintained. Since Bragg confinement and creation of a mini-gap energy state is sensitive to the value of the carrier effective mass, the system is also an effective mass filter for light holes.
