Increasing organic vertical carrier mobility for the application of high speed bilayered organic photodetector
TLDR
In this article, the vertical carrier mobility of bilayered organic photodiodes was investigated for the first time, and the influence of deposition rate on vertical hole mobility of pentacene film was discussed.Abstract:
The direct influence of the vertical carrier mobility on the frequency response of bilayered organic photodiodes (PDs) is investigated for the first time. With fullerene as the acceptor material, changing vertical hole mobility from 2.3×10−5 to 2.8×10−4 cm2/V s increases PD bandwidth from 10 to 80 MHz under a 4 V operation. The influence of deposition rate on vertical hole mobility of pentacene film is also discussed. Our results facilitate the application of bilayered organic PDs on the detection of very-high-frequency optical signals.read more

Correlated growth in ultrathin pentacene films on silicon oxide: Effect of deposition rate
TL;DR: In this article, the authors studied the growth mechanism of pentacene thin films on silicon dioxide (SiO2) using atomic force microscopy and demonstrated that the rate dependence of island nucleation has important implications for the density of grain boundaries, which may play an important role in the transport mechanism.
