Observation of type-I and type-II excitons in strained Si/SiGe quantum-well structures
The authors report photoluminescence (PL) measurement on a series of SiSiGe quantum-well structures that had different internal strain distributions. When each sample was placed in a high magnetic field, the field-dependent energy shift of the relevant PL peaks revealed either type-I or type-II exci...
