High Charge Carrier Mobilities and Lifetimes in Organolead Trihalide Perovskites
Organolead trihalide perovskites are shown to exhibit the best of both worlds: charge-carrier mobilities around 10 cm2 V−1 s−1 and low bi-molecular charge-recombination constants. The ratio of the two is found to defy the Langevin limit of kinetic charge capture by over four orders of magnitude. This mechanism causes long (micrometer) charge-pair diffusion lengths crucial for flat-heterojunctio...
متن کاملOptical measurements of charge-carrier mobilities in photorefractive sillenite crystals
Photorefractive crystals exhibit large optical nonlinearities1 and have great potential in optical data processing.2 The extrinsic photorefractive effect in these electro-optic and photoconductive materials is rather well understood. The band-transport model' has been successfully employed to describe photorefraction in crystals such as the sillenite compounds, Bi12SiO2 0 and Bi12GeO 2 0 (BGO)....
متن کاملGiant intrinsic carrier mobilities in graphene and its bilayer.
We have studied temperature dependences of electron transport in graphene and its bilayer and found extremely low electron-phonon scattering rates that set the fundamental limit on possible charge carrier mobilities at room temperature. Our measurements show that mobilities higher than 200 000 cm2/V s are achievable, if extrinsic disorder is eliminated. A sharp (thresholdlike) increase in resis...
متن کاملUnified description of charge-carrier mobilities in disordered semiconducting polymers.
From a numerical solution of the master equation for hopping transport in a disordered energy landscape with a Gaussian density of states, we determine the dependence of the charge-carrier mobility on temperature, carrier density, and electric field. Experimental current-voltage characteristics in devices based on semiconducting polymers are excellently reproduced with this unified description ...
متن کاملThe Bulk Carrier Maximum Optimal Ship Size
The main objective of this paper is to investigate the economical limit for the ships’ increase in size. Ship size is one factor out of many that affect the investors in the shipping business. The paper seeks to reassess the validity of well-established theoretical frameworks, which support the concept of depending on the increase in size of ships prompted by economies of scale. The investigati...
