Self-assembled graphene/BUBD-1 hybrids for ultrasensitive organic phototransistors

Abstract

Organic molecules have attracted intense attention as the promising candidates in future large-area, low manufacturing cost and flexible optoelectronic devices. However, limited to their short exciton diffusion length, low mobility...

Flexible near-infrared polarized photodetector based on CuPc single crystal grown by microspacing in-air sublimation

“…18,22,31,32 The photocurrent gain as a function of frequency was also recorded by a home-built high-frequency oscilloscope set-up, at zero gate bias. 33 The cut-off frequency at −3 dB, which is the point where the photocurrent signal was reduced by 2, was measured at about 4 kHz (Fig. 3d).…”

Organic photodetectors based on pentacene single crystals with fast response and flexibility

“…[9][10][11][12] In terms of optical properties, they exhibit a larger absorption coefficient than that of inorganic semiconductors, which endows them with superior photoelectric properties. 13,14 Furthermore, they are more ecofriendly that is of significance for future green electronic devices. 15 In fact, OSCs are becoming key elements in the preparation of flexible, printable, and scalable electronics and optoelectronics.…”
