摘要

We grew n-type arsenic (As)-doped single-crystal diamond layers using tertiarybutylarsine as an As source. The n-type conduction of the As-doped layers was confirmed both in Hall measurements and from the current-voltage characteristics of the diodes. In the As-doped layers, electron concentration increased with As concentration in the layers. The ionization energy of the As donor decreased from 1.6 to 0.7 eV with As concentration from 1 × 10~(17) to 9 × 10~(19)cm~3. A diamond p-n junction diode with an n-type As-doped layer exhibited a rectification ratio of ~1000 at ±10V at room temperature.
