Examples of Using DOPED in a Sentence

• Some Zener diodes have an abrupt, heavily doped p–n junction with a low Zener voltage, in which case the reverse conduction occurs due to electron quantum tunnelling in the short distance between p and n regions − this is known as the Zener effect, after Clarence Zener.
• Following his PhD, Mansfield was invited to postdoctoral research with Charlie Slichter at the University of Illinois at Urbana–Champaign, where he carried out an NMR study of doped metals.
• Payment records from Beloki as well as his race schedule were found in Eufemiano Fuentes' possession in his office; however, Beloki denies any claim he doped with Fuentes.
• Cadmium was commonly used in the phosphors of VFDs in the past, but the current RoHS-compliant VFDs have eliminated this metal from their construction, using instead phosphors consisting of a matrix of alkaline earth and very small amounts of group III metals, doped with very small amounts of rare earth metals.
• To reduce weight and save aluminium, much of the wing was made of plywood and fabric, while the fuselage was of metal-tube construction with wooden spars and covered with doped fabric, with heavy bracing in the floor to support the payload.

• Undoped and doped ceria also exhibit high electronic conductivity at low partial pressures of oxygen due to reduction of the cerium ion leading to the formation of small polarons.
• Rare earth elements such as neodymium and erbium can be doped into YAG as active laser ions, yielding Nd:YAG and Er:YAG lasers, respectively.
• In a traditional solid-state semiconductor, a solar cell is made from two doped crystals, one doped with n-type impurities (n-type semiconductor), which add additional free conduction band electrons, and the other doped with p-type impurities (p-type semiconductor), which add additional electron holes.
• Conventional silica-based AWGs, as illustrated in the figure above, are planar lightwave circuits fabricated by depositing layers of doped and undoped silica on a silicon substrate.
