The use of supersonically injected pulses of phosphine to achieve uniform and high levels of n-type doping in Si during gas-source molecular beam epitaxy is demonstrated. Uniform n-type doping up to levels of 5×1019 cm-3 is obtained. SiGe/Si junction diodes made with this doping technique show good doping profiles and rectifying characteristics.
