Wavelength extension in GaSbBi quantum wells using delta-doping
Journal article, 2018

Delta doped GaSbBi quantum wells (QWs) grown by molecular beam epitaxy was investigated to extend light emission wavelength at room temperature with the Bi content of 7.0%. The delta-doped GaSbBi QWs transition energy shifts up to 47.0 meV with increasing the Te dopant concentration from 0 to 4.56 × 10 12 cm −2 , resulting in maximum light emission of 2.42 μm, without obvious degradation of optical quality. The temperature coefficient of the band-gap for the delta-doped QW is only 0.099 meV/K compared with 0.265 meV/K from the undoped GaSbBi reference QW.
