- Abstract
A p- i- n light-emitting diode (LED) structure with InGaAs/GaAs quantum wells has been manufactured by combining the vapor phase epitaxy and laser ablation methods. The obtained heterostructures exhibit a negative differential resistance and the magnetodiode effect at 77 K. The proposed LED structure admits (i) switching from the low- to high-resistance state by applied pulsed bias voltage and (ii) electroluminescence quenching by external magnetic field.
