Title: Carbon nanotube quantum dots on hexagonal boron nitride

Abstract

We report the fabrication details and low-temperature characteristics of carbon nanotube (CNT) quantum dots on flakes of hexagonal boron nitride (hBN) as substrate. We demonstrate that CNTs can be grown on hBN by standard chemical vapor deposition and that standard scanning electron microscopy imaging and lithography can be employed to fabricate nanoelectronic structures when using optimized parameters. This proof of concept paves the way to more complex devices on hBN, with more predictable and reproducible characteristics and electronic stability.

  • The band structure of hexagonal boron nitride (BN) has been calculated using an [ital ab] [ital initio] linear combination of pseudoatomic-orbitals method. The calculated band structure confirms a previous finding that this material is an indirect band-gap insulator and has two empty interlayer bands. Projected densities of states are compared with the experimental x-ray emission spectra of B and N [ital K] edges and the agreement is good. This good agreement between the present ground-state calculation and the experimental x-ray emission spectra supports our previous finding that there should be very little valence electron relaxation effect on x-ray emission spectra.more » A real-space Green's function technique and the [ital Z]+1 approximation have been used to calculate the exciton spectra of B and N [ital K] edges. The first peak at 192 eV in B [ital K] edge is found to be a bound exciton with a binding energy of 1.7[plus minus]0.4 eV. Only resonance is found for the N [ital K] edge. The calculated exciton spectra agree very well with the experimental quantum-yield and electron-energy-loss spectra.« less
  • Single crystalline, two dimensional (2D) layered insulator hexagonal boron nitride (h-BN), is demonstrated as an emerging material candidate for surface passivation on mesoporous TiO{sub 2}. Cadmium selenide (CdSe) quantum dot based bulk heterojunction (BHJ) solar cell employed h-BN passivated TiO{sub 2} as an electron acceptor exhibits photoconversion efficiency ∼46% more than BHJ employed unpassivated TiO{sub 2}. Dominant interfacial recombination pathways such as electron capture by TiO{sub 2} surface states and recombination with hole at valence band of CdSe are efficiently controlled by h-BN enabled surface passivation, leading to improved photovoltaic performance. Highly crystalline, confirmed by transmission electron microscopy, dangling bond-freemore » 2D layered h-BN with self-terminated atomic planes, achieved by chemical exfoliation, enables efficient passivation on TiO{sub 2}, allowing electronic transport at TiO{sub 2}/h-BN/CdSe interface with much lower recombination rate compared to an unpassivated TiO{sub 2}/CdSe interface.« less
  • According to recent experiments, atomically thin hexagonal boron nitride and graphene are permeable to protons and deuterons (and not to other atomic species), and the experimental estimates of the activation energy are lower than the theoretical values by about 0.5 eV for the isolated proton-membrane transfer model. Our analysis of the electronic potential energy surfaces along the normal to the transmission direction, obtained using correlated electronic structure methods, suggests that the aqueous environment is essential to stabilize the proton { as opposed to the hydrogenatom { transmission. Therefore, the process is examined within a molecular model of H 2O {more » H(D) + { material { H 2O. Exact quantum-mechanical scattering calculations are performed to assess the relevance of the nuclear quantum eects, such as tunneling factors and the kinetic isotope eect (KIE). Deuteration is found to aect the thermal reaction rate constants (KIE of 3-4 for hexagonal boron nitride and 20-30 for the graphene) and to eectively lower the barriers to the proton transfer by 0.2 and 0.4 eV for the two membranes, respectively. This lowering eect is reduced for the deuteron by approximately a factor of three. A more comprehensive description of the proton transmission is likely to require an extended explicit aqueous environment.« less
  • The authors study the nature of defects that occur under certain conditions in the structure of hexagonal boron nitride to the lattice of the cubic modification. Its use as starting material for the preparation of the cubic modification of boron nitride represents the base of modern ultrahard tool materials. The method INDO and the VIKING program have been used to calculate the hypothetic molecule which represents a fragment of one hexagonal boron nitride layer, consisting of three hexagons, with one dope carbon atom replacing a nitrogen atom. The authors point out that the analogous procedure can be used not onlymore » to calculate the dope centers but also the nitrogen vacancies and the centers formed when boron nitride is irradiated with an electron beam on an accelerator with a voltage of 550 kV.« less
