Subpicosecond carrier transport in GaAs surface-space-charge fields.
Above-band-gap pulsed optical excitation of electron-hole pairs within the surface-space-charge region of semiconductors alters the surface-space-charge field via free-carrier transport. We report on the direct observation of this ultrafast transient screening and the associated charge-carrier transport by applying reflective electro-optic sampling (REOS) with subpicosecond time resolution to (...
متن کاملCharge-carrier transport in amorphous organic semiconductors
Organic semiconductors have been extensively studied ever since the successful fabrication of organic light-emitting diodes (OLED).4 2-44 Due to their success, it is becoming increasingly important to understand the theory behind the properties of organic materials. In order to exploit all the advantages of implementing organic materials to construct devices, a detailed understanding of charge-...
متن کاملSelf-assembled ErAs islands in GaAs: Growth and subpicosecond carrier dynamics
We report the growth of self-assembled ErAs islands embedded in GaAs by molecular beam epitaxy. The nucleation of ErAs on GaAs occurs in an island growth mode leading to spontaneous formation of nanometer-sized islands. Several layers of ErAs islands separated by GaAs can be stacked on top of each other to form a superlattice. X-ray diffraction shows superlattice fringes from such samples. Pump...
متن کاملSubpicosecond carrier dynamics in low-temperature grown GaAs on Si substrates
This letter describes time-resolved differential reflection measurements on low-temperature grown GaAs on ~100! Si substrates. The carrier recombination depends sensitively on growth and anneal conditions. The differential reflectance signals of samples annealed at 600 °C are dominated by an exponential subpicosecond transient, which can be as short as 370 fs. Optical microscopy and atomic forc...
متن کاملField Dependent Charge Carrier Transport for Organic Semiconductors at the Time of Flight Configuration
In this paper, we used the time-of-flight (TOF) of a charge packet, that injected by a voltage pulse to calculate the drift velocity and mobility of holes in organic semiconducting polymers. The technique consists in applying a voltage to the anode and calculating the time delay in the appearance of the injected carriers at the other contact. The method is a simple way to determine the charge t...
