Low temperature annealing of electron irradiated germanium
N-type germanium (4.X 1014 Sb/cm3) has been irradiated with 1.1 MeV electrons at SOK. The defects produced have been studied by measuring the voltage-dependent capacitance of a metal-germanium junction formed at the surface of a germanium sample. These measurements were made at lOoK and directly …

An ultrasonic study of point defects in electron-irradiated P-type silicon
… An exploratory ultrasonic study is performed on electron-irradiated Bdoped and Al-doped silicon. Neutral substitutional boron is detected before irradiation, as expected from previous ultrasonic studies on unirradiated silicon. This defect produces both resonance and relaxation. Similar effects …

An Ultrasonic Study of Impurity-Interstitial Complexes in Electron Irradiated Aluminum-Silicon and Aluminum-Silver
… of solute self interstitial complexes in electron irradiated (T -monoclinic defect symmetry is present. The annealing, during Stage II, of this defect species follows a first order rate equation which has a prefactor proportional to the solute concentration. The diaelastic effect …

An ultrasonic study of impurity-interstitial complexes in electron irradiated Al-Si and Al-Ag
… of solute self interstitial complexes in electron irradiated (T < 70 K) dilute Al-Ag and Al-Si alloys. In both alloy systems, a similar attenuation peak structure is observed. This peak structure strongly suggests that in both alloys, a defect species of <110>- monoclinic defect symmetry …

SPACE CHARGE LIMITED DIELECTRIC BREAKDOWN, OR: HOW I LEARNED TO STOP WORRYING AND LOVE APPROXIMATIONS
… decades of research. In this work, breakdown in electron irradiated polymethyl methacrylate is described by a new 1D space charge limited front (SCLF) model that reconceives breakdown as a propagating front rather than a diffuse event. To quantify embedded charge distributions and validate model …

Quantifying radiation damage through stored energy released during defect annealing in metals
… technique. For example, transmission electron microscopy (TEM) is unable to detect the smallest and most numerous defects in irradiated metals. Instead of spatial characterisation, defects can be detected and quantified through their excess energy. Previous measurements of stored …

The effects of ionising radiation on polypropylene
… and atactic polypropylene were δ and electron irradiated to doses of up to 20 megarad. Irradiations weremainly made in air. A series of other polymers were also irradiated in a preliminary survey. Molar mass measurements are used to measure the radiationyield for chain scission G (s). …

Interstitial-impurity interactions in copper-silver and aluminum-magnesium alloys
… interstltials and oversized impurities in electron-irradiated aluminum and copper. Measurements were taken of the ultrasonic attenuation (at 10 and 30 MHz) and resonant frequency (at 10 MHz) in single crystal sample s of Cu-Ag and AI-Mg. A variety of peaks appeared in both materials in …
