Here, we theoretically and experimentally investigate the impact of a high-$\kappa $ layer inserted between graphene and p-Si in a graphene/Si junction. We have achieved 86-fold and 222-fold reductions in a specific contact resistivity ($\rho _{c}$ ) by inserting 1-nm-thick Al2O3 and 2-nm-thick TiO2 in the graphene–semiconductor junction, respectively, corresponding to lowering the effective barrier...
We fabricated Si QPSK and PAM modulators with photonic crystal slow light waveguides and interleaved p/n junction, both of which have footprints less than 1 mm2. 30–35 Gbps operation were observed in 300–450 μm devices.
We observed the avalanche photodiode operation through defect levels at telecom band in Si photonic crystal slow light modulator. Maximum responsivity was 0.71 A/W with 350 avalanche gain. The eye opened at 20 Gbps.
