Abstract: A new MSM photodetector, including a photoabsorbing layer of ternary or quaternary III-V compound semiconductor material, is disclosed. This new photodetector is significant because it exhibits a relatively small dark current and a correspondingly large signal-to-noise ratio. Moreover, the photodetector is readily integrable with electronic integrated circuits and is relatively easy to fabricate.

Abstract: An equipment rack is disclosed whose frame member arms include protrusions, or a protrusion and a flange, that serve a dual function. First, the protrusions, or protrusion and flange, serve to define channels suitable for receiving a cable restraint device which serves to separately bundle cables according to type and/or function. Second, the protrusions serve as keyways along which additional, movable frame members slide telescopically to achieve a rack extendible to a wide variety of heights. Preferably, the inventive rack is of aluminum, resulting in a rack that is essentially as sturdy as the conventional steel racks but significantly lighter and easier to install.
Abstract: A method for fabricating a device which includes a tantalum silicide structure, and which is essentially free of conductive etch residues, is disclosed. The method includes the steps of depositing tantalum and silicon onto a substrate, patterning the tantalum and silicon, and then sintering the patterned tantalum and silicon to form a patterned layer of tantalum silicide.
