Title: Nondestructive method for analyzing total porosity of thin sections
Inventor: SMITH MICHAEL P
IPC: G01N15/08
Filed: 1988-05-31
Granted: 1991-07-02
Abstract: ABSTRACT Total porosity of impregnated thin sections can be measured using X-ray fluorescence.  The technique requires an impregnating fluid which contains an ele-ment not contained in more than trace quantities by the rock.  By measuring the intensity of fluorescence generated by bombarding the impregnated thin section with sufficiently energetic X-rays and rationing that intensity to the intensity of fluorescence generated by subjecting a sample containing only epoxy to the same conditions, and scaling the resulting measures of fluorescence, a measure of total effective porosity is produced.

Title: Bipolar hot electron transistor
Inventor: LEVI ANTHONY F J
IPC: H01L29/36
Filed: 1989-07-06
Granted: 1992-06-16
Abstract: BIPOLAR HOT ELECTRON TRANSISTOR Abstract A hot electron transistor (HET) comprising features that can result in substantially improved device characteristics is disclosed. Among the features is a highly doped (typically more than about 1020cm-3) thin base region, a thin (typically less than about 100 nm) collector depletion region, and a highly doped (typically more than about 1019cm-3) collector contact region. Ballistic transport through the base region is possible, despite the high doping level, because the inelastic scattering rate can be relatively low in at least some highly doped compound semiconductors such as GaAs, AlGaAs, InGaAs, or InP. The elastic scattering rate in the base region can be relatively low if the dopant atoms have an appropriate non-random distribution. Techniques for achieving such a distribution are disclosed. Transistors according to the invention are expected to find advantageous use in applications that demand high speed, e.g., in repeaters in high capacity optical fiber transmission systems.
