Simulation of full-color III-nitride LED with intermediate carrier blocking layers


Intermediate carrier blocking layers (ICBLs) adjacent to optically active quantum wells (QWs) are used for tailoring the output color spectra in multi-color III-nitride light-emitting diode (LED). We show that the ICBL active region design can efficiently balance the initially asymmetric supply of electrons and holes to optically active QWs and provide tunable LED emission in full visible optical range.
