This paper relates to the use of a thin film of re-crystallized (polycrystalline) silicon as a low-pass rejection filter in the ultraviolet light range and, more particularly, to the use of this layer as a protective layer for semiconductor diodes. T

In this paper, we present an integrated Coulter counter that applies a liquid aperture. The Coulter aperture is defined by a non-coaxial sheath of a conductive sample liquid that is surrounded on three sides by a non-conductive sheath liquid. The mai
