TL;DR: The cyclic voltammetric and kinetic data presented can serve as a benchmark for research groups evaluating the electrochemical properties of semimetallic (i.e., conductive), hydrogen-terminated, polycrystalline diamond.
Abstract: Standard electrochemical data for high-quality, boron-doped diamond thin-film electrodes are presented. Films from two different sources were compared (NRL and USU) and both were highly conductive, hydrogen-terminated, and polycrystalline. The films are acid washed and hydrogen plasma treated prior to use to remove nondiamond carbon impurity phases and to hydrogen terminate the surface. The boron-doping level of the NRL film was estimated to be in the mid 1019 B/cm3 range, and the boron-doping level of the USU films was ∼5 × 1020 B/cm-3 based on boron nuclear reaction analysis. The electrochemical response was evaluated using Fe(CN)63-/4-, Ru(NH3)63+/2+, IrCl62-/3-, methyl viologen, dopamine, ascorbic acid, Fe3+/2+, and chlorpromazine. Comparisons are made between the apparent heterogeneous electron-transfer rate constants, koapp, observed at these high-quality diamond films and the rate constants reported in the literature for freshly activated glassy carbon. Ru(NH3)63+/2+, IrCl62-/3-, methyl viologen, a...

TL;DR: In this paper, the authors investigated the self-decomposition of Ta(OC{sub 2}H{sub 5} )-sub 5 O(sub 5) and water as precursors for atomic layer epitaxy (ALE).
Abstract: Ta{sub 2}O{sub 5} thin films have been used in a number of applications such as dielectric materials for storage capacitors and thin film transistors, antireflection coatings for solar cells, optical waveguides, and filters chemical sensors, as well as corrosion resistant materials. The deposition of thin Ta{sub 2}O{sub 5} films by atomic layer epitaxy (ALE) was investigated in the temperature range of 150 to 450 C using Ta(OC{sub 2}H{sub 5}){sub 5} and water as precursors. Because of the thermal self-decomposition of Ta(OC{sub 2}H{sub 5}){sub 5} the self-limiting ALE growth was achieved only below 350 C. All the films grown were amorphous as examined by X-ray diffraction analysis. The films grown at 250 and 325 C were stoichiometric within the accuracy of Rutherford backscattering spectrometry and contained 4 and 0.6 atom percent (a/o) hydrogen as determined by nuclear reaction analysis, respectively. Except for the outermost surface, the content of carbon residues was below 3 a/o as analyzed by X-ray photoelectron spectroscopy. The films exhibited smooth surfaces as observed by scanning electron microscopy and relatively uniform thicknesses with 7% deviation in the gas flow direction. The refractive index of the films increased with deposition temperature stabilizing at 2.23 at temperatures higher than 300more » C. The permittivities for the films grown at 250 and 325 C were 21 and 25, respectively, and leakage current densities at 1 MV/cm electric field were 4.0 and 2.3 mA/cm{sup 2}, respectively.« less
