New experimental study of heavy ion and proton induced SEU at reduced voltage (i.e. reduced critical charge) reveals interesting results. It is shown that the heavy ion cross section and microprobe mapping scale like the threshold LET and the parameter, wh ...
B-doped diamond films were deposited by large-area hot filament chem. vapor deposition (HFCVD) on Si and different industrial electrode materials, such as Ti, Zr, Nb, Ta, W, and graphite, with areas up to 50 * 60 cm2. B-doping levels ranging from 50 to sev ...
We use molecular dynamics to analyze the dependence on the impact angle of the distribution of defects originated by the deposition of a Ag/sub 19/ cluster on Pd(100) at initial kinetic energies 0.1, 2, 20 and 95 eV. For increasing energy the cluster under ...
Particle contamination formed in reactive plasmas imposes an upper limit on the rate for particle-free deposition. Conversely, these plasmas could be exploited to produce nanometric clusters and particles for various applications. Infrared absorption spect ...

Nitrogen additions as NH4NO3 corresponding to 0 (N0), 1 (N1), 3 (N3) and 10 (N10) g N m(-2) yr(-1) were made to Sphagnum magellanicum cores at two-week intervals in situ at four sites across Europe, i.e. Lakkasuo (Finland), Mannikjarve (Estonia), Moidach M ...
Microcrystalline silicon (μc-Si:H) of truly intrinsic character can be deposited by plasma-enhanced chemical vapor deposition (PECVD) when dichlorosilane (SiH2Cl2) is added. A dark conductivity of 1.6×10-8 S/cm and an activation energy of 0.62 eV are obtai ...
Single crystals of layered semiconductors such as WS2 and MoS2 have already proven their efficiency as active elements in photovoltaic cells. Due to their high optical absorption coefficient in the visible range, these materials could be used in the form o ...
We study the deposition of Ag ions, and size selected Ag/sub 7/ and Ag/sub 19/ cluster ions on Pd(100) at total kinetic energies of 20 eV and 95 eV using thermal energy atom scattering and molecular dynamics simulations. We find that at all energies Ag ato ...
When silicon thin films are deposited by plasma enhanced chemical vapour deposition in a plasma regime close to that of the formation of powder, a new type of material, called polymorphous silicon (pm-Si), is obtained. We present here the optoelectronic an ...
In situ Fourier transform infrared (FTIR) absorption spectroscopy has been used to determine the fractional depletion of silane in a radio-frequency (ri) glow discharge. The technique used a simple single-pass arrangement and was implemented in a large-are ...
