[Q]: When these devices exploit their voltage-dependent variable capacitance they are known as varactors. Barring the creation of local hot spots, a non-destructive avalanche current is produced by electron-hole pair propagation when the electric field within the (*) depletion region of these devices reaches a critical value. Majority carriers exist in an energy state greater than the Fermi energy in the Schottky barrier variety and those that operate in reverse breakdown are named after Zener. For 10 pointsname these devices that allow current to pass in only one direction.
[A]: Science


[Q]: In one story about this figure, he forgives a man who murdered a woman because she wanted to have sex; he also converts Charisius and Mygdonia before being put to death by Misdaeus. According to tradition, he received the girdle of the Virgin Mary after she was assumed bodily into Heaven, and he is credited with authorship of the "Hymn of the Pearl. " His namesake Gospel describes Jesus killing a playmate for having bumped into Jesus's shoulder, while in John 14:5 he asks Jesus, "How can we know the way" at the Last Supper. Also called Didymus, meaning "Twin," and famous for spreading Christianity to India, this is, FTP, what apostle who asked to touch Jesus's wounds after the resurrection, leading to the epithet "Doubting"
[A]: Social Science


[Q]: The paper explaining this phenomenon begins with a section critical of the theory of blackbody   radiation, showing that an integral of energy with respect to volume equals infinity. That problem is  solved by assuming that energy "is discontinuously distributed in space." Some of the measurements   of this effect, which used to be associated with ultraviolet light, were made by Philipp Lenard, who  discovered that light intensity did not impact the amount of voltage required to stop rays produced  by light striking metal. Name this effect explained when the Planck hypothesis was applied by Albert  Einstein, leading to Einstein's Nobel Prize.
