The emergence of halide perovskites in photovoltaics has diversified the research on this material family and extended their application towards several fields in the optoelectronics, such as photoand ionizing-radiation-detectors. One of the most basic characterization protocols consist on measuring the dark current-voltage (J − V) curve of symmetrically contacted samples for identifying the different regimes of spacecharge-limited current (SCLC). Customarily, J ∝ V indicate the Mott-Gurney law…

Unravelling the role of vacancies in lead halide perovskite through electrical switching of photoluminescence
The role of defects in the carrier recombination dynamics in photoluminescence experiments is revealed and a model to describe it is presented, which accounts for the time dependence of electrical current due to the ion-induced doping modification.
Space-charge-limited electron and hole currents in hybrid organic-inorganic perovskites
The results reveal that in the solution processed MAPbI3 thin films transport of electrons dominates over holes, and it is shown that the direction of the hysteresis in the current-voltage characteristics provides a fingerprint for the sign of the dominant moving ionic species.
Understanding Dark Current-Voltage Characteristics in Metal-Halide Perovskite Single Crystals
Hybrid halide perovskites have great potential for application in optoelectronic devices. However, an understanding of some basic properties, such as charge-carrier transport, remains inconclusive,
Exploring the validity and limitations of the Mott-Gurney law for charge-carrier mobility determination of semiconducting thin-films.
Using drift-diffusion simulations, the voltage dependence of the dark current in single carrier devices typically used to determine charge-carrier mobilities is investigated and it is shown that, depending on the thickness of the semiconductor layer and the size of the injection barriers, the two linear current-voltage regimes can dominate the whole voltage range, and the intermediate Mott-Gurney regime can shrink or disappear.
Long-range ballistic propagation of carriers in methylammonium lead iodide perovskite thin films
The performance of semiconductor devices is fundamentally governed by charge-carrier dynamics within the active materials 1 – 6 . Although advances have been made towards understanding these dynamics
Electrical Methods to Elucidate Charge Transport in Hybrid Perovskites Thin Films and Devices.
This work aims to summarize the electrical transport properties of perovskite thin films by using (i) impedance spectroscopy (IS), (ii) space charge limited current (SCLC), (iii) field-effect transistors (FETs) and (iv) time-of-flight (TOF) methods.
Enhanced Ballistic Transport of Charge Carriers in Alloyed and K-Passivated Alloyed Perovskite Thin Films
The ballistic transport is proposed to be limited by nanoscale trap clusters at grain boundaries and interfaces, which can be passivated via chemical treatments to enhance the ballistic transport length, which implies that further enhancements are possible as passivation methods are improved.
Mobile Ion-Driven Modulation of Electronic Conductivity Explains Long-Timescale Electrical Response in Lead Iodide Perovskite Thick Pellets.
These findings point to a coupling of ionic and electronic properties as a dynamic doping effect caused by moving ions that act as mobile dopants, as far as long-timescale current stabilization is concerned.
Ballistic transport in high electron mobility transistors
A general ballistic FET model that was previously used for ballistic MOSFETs is applied to ballistic high electron mobility transistors (HEMTs), and the results are compared with experimental data

At low temperature in a high mobility semiconductor such as GaAs the transit time of electrons across a short device may become comparable or even less than the time between collisions. Under such
