(LSMO) film, while the transport of 10-nm LSMO manganite layer can be tuned with applied electric field using various field effect configurations. 10-nm LSMO layer shows a large change in resistance with the application of voltage, i.e., exhibiting colossal electroresistance (CER) ∼ 100% (negative) and large positive electroresistance (ER) ∼ 2683% under 4.5 V at room temperature. The variation scenario in 10-nm LSMO transport has been discussed on the basis of electric-field-induced modifications in the charge carrier density and electronic states.
