Defining Excipients â¢ Excipients are defined like any other material â¢ Excipients are often multi-substance ingredients (colorants, flavors, fragrances) â Each substance should be defined â¢ Excipients are often the most difficult substances to define â No official naming body that defines most excipients â Insufficient information in pharmacopeias â Manufactures are inconsistent in the type information
Lightly and moderately doped semiconductors are referred to as extrinsic. A semiconductor doped to such high levels that it acts more like a conductor than a semiconductor is referred to as degenerate. In the context of phosphors and scintillators, doping is better known as activation.he effects of semiconductor doping were long known empirically in such devices as crystal radio detectors and selenium rectifiers. However, the process was formally first developed by John Robert Woodyard working at Sperry Gyroscope Company during World War II.
