Title: Monolayer borophene electrode for effective elimination of both the Schottky barrier and strong electric field effect

Abstract

The formation of Schottky barriers between 2D semiconductors and traditional metallic electrodes has greatly limited the application of 2D semiconductors in nanoelectronic and optoelectronic devices. In this study, metallic borophene was used as a substitute for the traditional noble metal electrode to contact with the 2D semiconductor. Theoretical calculations demonstrated that no Schottky barrier exists in the borophene/2D semiconductor heterostructure. The contact remains ohmic even with a strong electric field applied. This finding provides a way to construct 2D electronic devices and sensors with greatly enhanced performance.

  • Spectral dependences of effective values of the real and imaginary parts of the low-frequency permittivity of the Cd{sub 1-x}Zn{sub x}Te crystals (x=0.12-0.16) with the Schottky barrier fabricated on the surface are measured. It is found that the boundary wavelengths of the characteristic portions of the measured dependences represented in the complex plane correspond to energies of photons, which cause the radical variations in the state of negatively charged and electrically neutral localized acceptor states. The variations in the energy spectrum of the localized states, which are determined by the magnitude and polarity of the electric bias applied to the Shottkymore » barrier, are found.« less
  • The results of a study on photoelectric properties of a Schottky barrier based on n-type CdP{sub 2} are considered. The effect of the barrier electric field on photocurrents caused by photoelectron emission from metal and optical generation of excess charge carriers in the semiconductor was studied. It was found that the dependence of the photocurrent on the light-modulation frequency is controlled by level recharging times at the interfaces between the space-charge and quasi-neutrality regions and between semiconductor and metal. Good agreement between the calculated and experimental results was achieved.
  • Effect of annealing on the electrical properties of 50 nickel Schottky contacts formed on a single 4H-SiC wafer has been studied. It is shown that annealing at 200 deg. C for 1 h favors homogenization of the metal-semiconductor heterointerface, which leads to a narrower scatter of such contact parameters as the ideality factor and effective barrier height. At higher annealing temperatures (350-450 deg. C) the scatter of these parameters again increases; presumably, this occurs because of the local chemical interaction of nickel with silicon carbide.
  • Although a Al/H{sub 2}tpp (5, 10, 15, 20-tetraphenylporphyrin) Schottky-barrier cell did not show a clear rectification property because of the large electric resistance of the H{sub 2}tpp solid, the rectification property was remarkably improved when o-chloranil was added into the H{sub 2}tpp solid. The short-circuit dark-current was observed for the Al/dye cells with the mixed solid in contrast to that with the pure H{sub 2}tpp solid, and it increased with increasing molar ratio (R) of o-chloranil to H{sub 2}tpp. Furthermore, a much larger photocurrent was observed for the mixed-solid cells than for the pure H{sub 2}tpp cell, but in themore » former cells in contrast to the latter cell, the open-circuit photovoltage was approximately the same as the open-circuit dark-voltage. These results indicate that the photocurrent of the mixed-solid cells was from the photocorrosion of the Al electrode. The short-circuit photocurrent action spectra obtained by irradiating from the Al side followed the absorption spectra of the dye solid films on the Al substrate below the R value of about 1, but above R = 1.5, a clear difference was observed in the spectra. This difference arises because a small amount of metal-free porphyrin dications, which is hardly detected by UV-visible spectra, was produced in the immediate neighborhood of the Al electrode when spin-coated with a larger R value because of dark-corrosion of aluminum by both assistance of the hydrogen bonds (between H{sub 2}tpp and o-chloranil) and the electric fields (in a Schottky barrier built during the spin coating). Thus the metal-free porphyrin dications efficiently underwent a photoinduced charge-separation by the potential gradient in the Schottky barrier.« less
  • We demonstrate a vertical field-effect transistor based on a graphene/MoSe{sub 2} van der Waals (vdW) heterostructure. The vdW interface between the graphene and MoSe{sub 2} exhibits a Schottky barrier with an ideality factor of around 1.3, suggesting a high-quality interface. Owing to the low density of states in graphene, the position of the Fermi level in the graphene can be strongly modulated by an external electric field. Therefore, the Schottky barrier height at the graphene/MoSe{sub 2} vdW interface is also modulated. We demonstrate a large current ON-OFF ratio of 10{sup 5}. These results point to the potential high performance ofmore » the graphene/MoSe{sub 2} vdW heterostructure for electronics applications.« less
