Schematic diagram of cross section of MGM-PD (inner electrodes width: ; outer electrodes width: ). DS schemes for MGM-PDs: (1) non-DS (with no DS in both inner and outer electrodes), (2) pp-DS (with B DS in both inner and outer electrodes), (3) np-DS (with As DS in inner electrode and B DS in outer electrode), and (4) nn-DS (with As DS in both inner and outer electrodes).
Dark current comparison between MGM-PDs with different DS strategies.
Schematic conduction and valence band profile in DS-MGM-PD with/without dopant segregation in two NiGe electrodes at positive bias for (a) MGM-PD without DS (non-DS), (b) MGM-PD with B segregation in two electrodes (pp-DS), (c) MGM-PD with B and As segregated separately in two NiGe electrodes (np-DS), and (d) MGM-PD with As segregation in two electrodes (nn-DS).
Measured photocurrent at wavelength of for DS-MGM-PD with nn-DS and np-DS. The inset is the photocurrent excluding dark current.
