文摘

In this work, we designed a two-dimensional BDJ model and used finite element method to compute the response photocurrent instead of analytic model used in previous studies. To take into consideration multiphysics aspects COMSOL is used to study the optical and electrical behaviour of a Buried Double Junction (BDJ) photodetector designed with CMOS technology, the optical study describes the propagation of electromagnetic waves through air, silicon dioxide and silicon layers, the semiconductor study gives us the photocurrent for the two buried junctions to an incident wavelength.
