Here, a coupling effect of pyro-phototronic and piezo-phototronic effect is utilized to fabricate a self-powered and broadband PD based on the MAPbI3single-crystal film/n-Si heterojunction. First, by using the pyro-phototronic effect derived from MAPbI3, the maximum photoresponsivity of the ...

P is the light power intensity and S is the effective sensitive areas, which are defined as the coverage areas of the interdigital Au electrodes by the MAPbI3 nanowires. Considering that the shot noise dominates the total noise in photoconductive photodetectors, normalized detectivity can be given...
There remains much room for growth on the fixed broadband front with Malaysia's penetration rate per 100 premises at 48.6% (+6.7pp YoY) in 1Q23. Dampener Malaysia's high mobile penetration rate (1Q23: 147.6% per 100 inhabitants) renders limited room for mobile service revenue growth. ...
MAPbI3Broadband PDsResponsivityDetectivityPhotoresponseNumerous structures have been reported in search of affordable self-powered broadband photodetectors, however with limited success. The hybrid perovskite heterostructures have been attracted great attention due to their advance optical and electrical properties...
The as-prepared MAPbI3 nanowires were used to fabricate photodetectors that exhibited a fairly high switching ratio of ~600, responsivity of 55 mA/W and normalized detectivity of 0.5 × 1011 jones under 532 nm light illumination (40 mW/cm2) at a very low bias voltage of 0.1 V. To the ...
