Surface conduction on insulating BaTiO3 crystal suggesting an intrinsic surface electron layer.
We report conduction measurements on the clean, free surface of transparent insulating BaTiO3 single crystals in high vacuum. We find that the insulating BaTiO3 crystals exhibit surface conductance that is dependent on the spontaneous polarization, whereas no conduction perpendicular to the surface is observed. The surface conduction shows semimetallic temperature dependence and persists down t...
متن کاملInsulating behavior at the neutrality point in single-layer graphene.
The fate of the low-temperature conductance at the charge-neutrality (Dirac) point in a single sheet of graphene on boron nitride is investigated down to 20 mK. As the temperature is lowered, the peak resistivity diverges with a power-law behavior and becomes as high as several megohms per square at the lowest temperature, in contrast with the commonly observed saturation of the conductivity. A...
متن کاملColossal electroresistance in ferromagnetic insulating state of single crystal
Colossal electroresistance (CER) has been observed in the ferromagnetic insulating (FMI) state of a manganite. Notably, the CER in the FMI state occurs in the absence of magnetoresistance (MR). Measurements of electroresistance (ER) and current induced resistivity switching have been performed in the ferromagnetic insulating state of a single crystal manganite of composition Nd0.7Pb0.3MnO3 (NPM...
متن کاملChiral Single Crystal Surface Chemistry
Several experiments have been performed to probe the enantiospecific properties of chiral single crystal surfaces. The surfaces chosen have been the (643) planes of Ag and Cu, both face centered cubic structures. The chirality of these surfaces arises from the handedness of their kinked step structures. These structures are such that the (643) and the (643) surfaces are related by mirror symmet...
متن کاملTwo-layer Crystal Square for Transistors on a Single Chip
The number of transistors on a chip plays the main role in increasing the speed and performance of a microprocessor; more transistors, more speed. Increasing the number of transistors will be limited due to the design complexity and density of transistors. This article aims to introduce a new approach to increasing the number of transistors on a chip. The basic idea is to construct two-layer cr...
