Surface Energy Band and Electron Affinity of Highly Phosphorous-doped Epitaxial CVD Diamond

Shutterless deposition of phosphorous doped microcrystalline silicon by Cat-CVD

In this paper we present results on phosphorous-doped c-Si:H by catalytic chemical vapour deposition in a reactor which internal arrangement does not include a shutter. An incubation phase of around 20 nm seems to be the result of the uncontrolled conditions that take place during the first stages of deposition. The optimal deposition conditions found lead to a material with a dark conductivit...

Z-contrast imaging and electron energy-loss spectroscopy analysis of chromium-doped diamond-like carbon films

Metal-doped diamond-like carbon films were produced for the purpose of an electrochemical nanoelectrode. In this study we use Z-contrast scanning transmission electron microscopy to directly observe metal cluster formation and distributions within the chromium-doped carbon films. At low doping ~;6 at. % Cr!, Cr is uniformly distributed within the C matrix; at high doping ~;12 at. % Cr!, Cr-rich...

Valence band states in diamond p-delta-doped quantum wells

The hole energy structure in boron delta-doped diamond is studied with the use of the 6 × 6 k · p Hamiltonian. The approach starts with a Thomas-Fermi-based description of the heavy, light and split-off hole states at the Brillouin zone center, and is extended to k 6= 0 points by using the obtained Γ-point solutions as a basis for the diagonalization that leads to the energy vs k relations corr...

Derivation of ionization energy and electron affinity equations using chemical hardness and absolute electronegativity in isoelectronic series

Chemical hardness () and absolute electronegativity () have important applications in chemistry. Inthe conceptual Density Functional theory (DFT), these concepts has been associated with electronicenergy and the relationship with ionization energy (I) and electron affinity (A) of these concepts hasbeen given. In this study, graphical method was used in order to see the relationship with the ato...
