The nucleation and growth of magnesium oxide (MgO) deposited using the ion beam-assisted deposition (IBAD) technique was investigated using a specially designed in-situ quartz crystal microbalance (QCM), which acted as the substrate during deposition

High temperature superconductor YBa 2 Cu 3 O 7-x thin films have been grown using in situ electron beam evaporation at deposition rates over 1-10 nm/s. The higher activity of atomic oxygen is being explored along with molecular oxygen at reduced pres

The realization of spin polarized tunnel devices made with CrO2, a theorized half-metallic ferromagnet, requires stringent control of surface and interface quality ideally obtainable via molecular beam epitaxy (MBE) growth. We have studied the MBE gr

Diode-laser-based atomic absorption (AA) sensors have been developed for direct measurement of atomic flux, based on both atomic density and velocity information, which is important for in situ monitoring and control of physical vapor deposition proc

We have demonstrated a lamp-based atomic absorption detection system at 120 nm for monitoring atomic nitrogen generation in microwave discharge. Atomic nitrogen flux and dissociation ratio were evaluated by the atomic absorption. Delivery of atomic n

Strong spin-orbit coupling in topological insulators results in the ubiquitously observed weak antilocalization feature in their magnetoresistance. Here we present magnetoresistance measurements in ultrathin films of the topological insulator Bi${}_{

In this retrospective review we assessed the frequency with which atypical glandular cells in cervical smears predict cervical glandular lesions. Asymptomatic patients (n=34) with one or more smears showing atypical glandular cells aand subsequent hi

We report the synthesis of superconducting MgB2 thin films grown in situ by molecular-beam epitaxy. Mg-rich fluxes are deposited with B flux by electron-beam evaporation onto c-plane sapphire substrates. The films exhibit c-axis oriented peaks of MgB
