Monte Carlo analysis of a lateral IBIC experiment on a 4H-SiC Schottky diode / Olivero, P ; Forneris, J ; Gamarra, P ; Jaksic, M ; Giudice, A Lo ; Manfredotti, C ; Pastuovic, Z ; Skukan, N ; Vittone, E
The transport properties of a 4H-SiC Schottky diode have been investigated by the Ion Beam Induced Charge (IBIC) technique in lateral geometry through the analysis of the charge collection efficiency (CCE) profile at a fixed applied reverse bias voltage. The cross section of the sample orthogonal to the electrodes was irradiated by a rarefied 4 MeV proton microbeam and the charge pulses have been recorded as function of incident proton position with a spatial resolution of 2 um.

The covariant electromagnetic Casimir effect for real conducting spherical shells / Razmi, H ; Abtahi, M
Using the covariant electromagnetic Casimir effect (previously introduced for real conducting cylindrical shells [1]), the Casimir force experienced by a spherical shell, under Dirichlet boundary condition, is calculated. The renormalization procedure is based on the plasma cut-off frequency for real conductors. [...]

Hybird of Quantum Phases for Induced Dipole Moments / Ma, Kai
The quantum phase effects for induced electric and magnetic dipole moments are investigated. It is shown that the phase shift received by induced electric dipole has the same form with the one induced by magnetic dipole moment, therefore the total phase is a hybrid of these two types of phase.

Existence and properties of the Navier-Stokes equations / Zhirkin, Alexey V
A proof of existence, uniqueness and smoothness of the Navier-Stokes equations is an actual problem, which solution is important for different branches of science. The subject of this study is obtaining the smooth and unique solutions of the three-dimension Stokes-Navier equations for the initial and boundary value problem. [...]

The role of the C2 gas in the emergence of C60 from the condensing carbon vapour / Ahmad, Shoaib ; Yaqub, Kashif ; Tasneem, Afshan
A model has been developed that illustrates the emergence of C60 from the condensing carbon vapor. It is shown to depend upon the decreasing heats of formation for larger cages, exponentially increasing number of isomers for fullerenes that are larger than C60, large cages buckling induced by the pentagon-related protrusions that initiate fragmentation, the structural instability induces fragmentation that shrinks large cages and an evolving gas of C2 that is crucial to the whole process.

Focused ion beam fabrication and IBIC characterization of a diamond detector with buried electrodes / Olivero, P ; Forneris, J ; Jaksic, M ; Pastuovic, Z ; Picollo, F ; Skukan, N ; Vittone, E
This paper reports on the fabrication and characterization of a high purity monocrystalline diamond detector with buried electrodes realized by the selective damage induced by a focused 6 MeV carbon ion beam scanned over a pattern defined at the micrometric scale. A suitable variable-thickness mask was deposited on the diamond surface in order to modulate the penetration depth of the ions and to shallow the damage profile toward the surface. [...]

Lateral IBIC characterization of single crystal synthetic diamond detectors / Giudice, A Lo ; Olivero, P ; Manfredotti, C ; Marinelli, M ; Milani, E ; Picollo, F ; Prestopino, G ; Re, A ; Rigato, V ; Verona, C et al.
In order to evaluate the charge collection efficiency (CCE) profile of single-crystal diamond devices based on a p type/intrinsic/metal configuration, a lateral Ion Beam Induced Charge (IBIC) analysis was performed over their cleaved cross sections using a 2 MeV proton microbeam. CCE profiles in the depth direction were extracted from the cross-sectional maps at variable bias voltage. [...]

The detection of quantal exocytic events from neurons and neuroendocrine cells is a challenging task in neuroscience. One of the most promising platforms for the development of a new generation of biosensors is diamond, due to its biocompatibility, transparency and chemical inertness. [...]

IBIC characterization of an ion-beam-micromachined multi-electrode diamond detector / Forneris, J ; Grilj, V ; Jaksic, M ; Giudice, A Lo ; Olivero, P ; Picollo, F ; Skukan, N ; Verona, C ; Verona-Rinati, G ; Vittone, E
Deep Ion Beam Lithography (DIBL) has been used for the direct writing of buried graphitic regions in monocrystalline diamond with micrometric resolution. Aiming at the development and the characterization of a fully ion-beam-micromachined solid state ionization chamber, a device with interdigitated electrodes was fabricated by using a 1.8 MeV He+ ion microbeam scanning on a homoepitaxial, grown by chemical vapour deposition (CVD).
