Abstract
We have presented the room-temperature persistent photoconductivity (PPC) effect in γ-InSe layered semiconductors. The PPC effect can be observed in the temperature range from room temperature down to 200 K, and the PPC decay is well described by a stretch-exponential function. The temperature-dependent PPC and performance of PPC decay indicate that the random local-potential fluctuations (RLPF) mechanism is responsible for PPC effect inγ-InSe. In addition, the PPC behavior at different temperature regions can be well explained by the percolation model associated with the RLPF mechanism.
期刊介绍：
Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged.
A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions.
The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
