A system of linear homogeneous algebraic equations for the coupling constant ratios of vector mesons to hadrons is derived by imposing the assumed asymptotic behavior upon the VMD pole parameterization of an hadron electromagnetic form factor. A similar system of equations with a simpler structure of the coefficients, taken as even powers of the vector-meson masses, is derived by means of integral superconvergent sum rules for the imaginary part of the considered form factor using its appropriate $\ ...

Development of SiGe HBTs in BiCMOS technology with both high f T and f MAX faces significant challenges. To increase f T , thinning the base and collector thickness is generally the first step to reduce the carrier transit times, but this increases the base resistance and the collector-base capacitance, which impacts f MAX negatively. Increasing collector doping is also often employed to increase f T , but this increases collector-base capacitance, which drives f MAX down. To overcome these limits, ...

Scaling silicon germanium heterojunction bipolar transistors (SiGe HBTs) to attain simultaneous increases in the figures of merit , f T and f MAX has necessitated a deep understanding of the inherent features of the process as it relates to the final device performance. The faceted nature of the base epitaxial growth on the periphery of the shallow trench isolation has been the focus of several investigations which have demonstrated the role it plays in the extrinsic collector-base capacitance. In ...

Scaling silicon germanium heterojunction bipolar transistors (SiGe HBTs) to attain simultaneous increases in the figures of merit, f T and f MAX has necessitated a deep understanding of the inherent features of the process as it relates to the final device performance. Layout variations in the location of the field polysilicon layer relative to the edge of the active silicon region, results in marked changes in the intrinsic device, with increases in f T /f MAX of 15/20GHz respectively.

There is no sign of saturation in accumulation of alien species (AS) introductions worldwide, additionally the rate of spread for some species has also been shown to be increasing. However, the challenges of gathering information on AS are recognized. Recent developments in citizen science (CS) provide an opportunity to improve data flow and knowledge on AS while ensuring effective and high quality societal engagement with the issue of IAS (Invasive Alien Species). Advances in technology, particularly ...

A self-aligned sacrificial emitter (SASE) process has been successfully developed in a BiCMOS technology. Selective epitaxy of SiGe originally developed for sub-100 nm CMOS nodes is used for a raised extrinsic base. Process integration includes building a sacrificial emitter pedestal using a CMOS gate-like etch, isolation of the emitter to extrinsic base by oxide CMP, and oxide recess etch to expose the emitter window for the in-situ doped emitter. Electrical results are shown to be comparable to ...
