← ScienceWhich outcome occurs when excessive manganese is integrated into a gallium arsenide crystal during Czochralski growth?
A)Reduced electron mobility at high frequencies✓
B)Increased thermal conductivity substantially above expectations
C)Enhanced electron-hole recombination emission spectrum
D)Increased crystal hardness tensile sheer resistance
💡 Explanation
Electron mobility decreases because introducing manganese causes increased ionized impurity scattering, therefore reducing electron acceleration in fields, rather than altering thermal or optical properties. Introducing more Mn impedes electron travel, resulting in the outcome.
