The Web site contains a number of BPA safety documents, notices and manuals, including anti doping policy, in Word format.
In modulation doping, facing layers of gallium arsenide and aluminum gallium arsenide squeeze electrons into an essentially two-dimensional electron gas, or 2DEG.
Stoichiometry, doping, defect chemistry and also ceramic microstructure often control ferroelectric properties in bulk materials.
A doping strategy will be evaluated for a selected ceramic such as partially or fully stabilized zirconia.
But if you add charge carriers by chemically doping them they become superconductors with transition temperatures of up to 135K.
