Abstract We discuss how the emission of electrons and ions during electron-beam-induced physical vapor deposition can cause problems in micro- nanofabrication processes. After giving a short overview different types radiation emitted from an electron-beam (e-beam) evaporator amount depends on parameters conditions, we highlight two phenomena more detail: First, unintentional shadow evaporation ...

Uniform clusters of Pt have been deposited on the surface of capping-agent-free CeO2 nanooctahedra and nanorods using electron beam (e-beam) evaporation. The coverage of the Pt nanocluster layer can be controlled by adjusting the e-beam evaporation time. The resulting e-beam evaporated Pt nanocluster layers on the CeO2 surfaces have a clean surface and clean interface between Pt and CeO2. Diffe...

Disordered carbon particulates were deposited on the surface of natural acid treated zeolite through graphite evaporation by electron beam to improve adsorption properties porous material. This study focuses development new material and not applications. The effect treatment deposition physical was investigated. zeolites characterized via spectroscopic microscopic methods, thermal analysis, gas...

High Energy collisions of nuclei usually lead to the emission of evaporation neutrons from both “beam” and “target” nuclei. At the RHIC heavy ion collider with 100GeV/u beam energy, evaporation neutrons diverge by less than 2 milliradians from the beam axis. Neutral beam fragments can be detected downstream of RHIC ion collisions (and a large aperture Accelerator dipole magnet) if θ ≤ 4 mr but ...

Transparent conducting tin oxide thin films have been prepared by electron beam evaporation and spray pyrolysis methods. Structural, optical and electrical properties were studied under different preparation conditions like substrate temperature, solution flow rate and rate of deposition. Resistivity of undoped evaporated films varied from 2⋅65 × 10 Ω-cm to 3⋅57 × 10 Ω-cm in the temperature ran...

Formation of planar heterojunction perovskite solar cells exhibiting both high efficiency and stability under continuous operation remains a challenge. Here, we show this can be achieved by using a defective TiO2 thin film as the electron transport layer. TiO2 layers with native defects are deposited by electron beam evaporation in an oxygen-deficient environment. Deep-level hole traps are intr...
