A light-emitting device is disclosed. The light emitting device includes an electron blocking layer, a hole blocking layer, wherein at least a portion of the hole blocking layer is arranged to have a compressive strain, and an active layer disposed between the hole blocking layer and the electron blocking layer.

Strained AlGaInP layers for efficient electron and hole blocking in light emitting devices

A light-emitting device is disclosed. The light emitting device includes an electron blocking layer, a hole blocking layer, wherein at least a portion of the hole blocking layer is arranged to have a compressive strain, and an active layer disposed between the hole blocking layer and the electron blocking layer. The active layer may include a first barrier layer arranged to have a tensile strain, a second barrier layer arranged to have a tensile strain, and a first well layer disposed between the first barrier layer and the second barrier layer. The active layer may also include a first unstrained barrier layer, a second unstrained barrier layer, and a second well layer disposed between the first unstrained barrier layer and the second unstrained barrier layer.
