Surface Emission And Band-Bending In Shallow Junction GaAs LEDs As Affected By Type Of Gas And Pressure Academic Article uri icon


  • The environment can affect optical and electronic properties of optoelectronic devices. Here, noticeable alterations in spectral shape and wavelength of peak emission in light emitting diodes are shown to occur with changes in environmental gas and pressure. A relationship between band bending and surface charge density is derived.
