The photogating effect in hybrid structures has manifested itself as a reliable and promising approach for photodetectors with ultrahigh responsivity. A crucial factor of the is built-in potential at interface, which controls separation harvesting photogenerated carriers. So far, primary efforts designing rely on discovering different materials developing multilayer structures, may raise problems compatibility standard semiconductor production line. Here, we report an enhanced monolayer...
Highly sensitive short-wave infrared (SWIR) detectors, compatible with the silicon-based complementary metal oxide semiconductor (CMOS) process, are regarded as key enabling components in miniaturized system for weak signal detection. To date, high photogain devices greatly limited by a large bias voltage, low-temperature refrigeration, narrow response band, and complex fabrication processes. Here, we demonstrate detectors working SWIR region at room temperature, which use graphene charge...
Abstract The hybrid structures of graphene with semiconductor materials based on photogating effect have attracted extensive interest in recent years due to the ultrahigh responsivity. However, responsivity (or gain) was increased at expense response time. In this paper, we devise a mechanism which can obtain an enhanced and fast time simultaneously by manipulating (MPE). This concept is demonstrated using graphene/silicon-on-insulator (GSOI) structure. An more than 10 7 A/W 90 µs were...
Abstract An analytical random and multipath transport (RMT) model for ordered organic semiconductors is developed based on the microscopic definition of mobility, Miller-Abraham hopping rate, central limit theorem (CLT). The RMT can take main factors affecting mobility in into account, including temperature, density, electric field, density states (DOS), structure. numerical results Gaussian DOS regarding relationship between show good agreement with simulation reported literature under a...

The thermoelectric properties of organic semiconductors are studied theoretically. Based on the Miller-Abrahams hopping model and concept genuine transport energy, we obtained analytic expressions carriers concentration, conductivity, Seebeck coefficient. Combining an exponential-type density states with clear cutting tail at some places, dependence coefficient carrier concentration temperature can be evaluated. numerical results optimized parameters describe experimental data well.
Although the drift-diffusion model (DDM) is fundamental in semiconductor physics and related fields, accurate solution of DDM unavailable over a long period time. The accurately analytically solved based on Fermi-Dirac statistics general mobility model. differences current values, carrier density, electric field functions between solution, other solutions, standard Scharfetter-Gummel (SG) scheme are evident. results for extracted from larger evidently different those SG scheme, Mott-Gurney...

A simple equation of state (EOS) in wide ranges pressure and temperature is constructed within the Mie—Grüneisen—Debye framework. Instead popular Birch—Murnaghan Vinet EOS, we employ a five-parameter cold energy expression to represent static EOS term, which can correctly produce cohesive without any spurious oscillations extreme compression expansion regions. We developed Padé approximation-based analytic Debye quasiharmonic model with high accuracy improves performance low region. The...
