- 論文の詳細を見る
We have succeeded in fabricating (001)-oriented diamond $ p$–$n$ junctions with good diode characteristics and realized UV light emission by current-injection at room temperature. As $ p$–$n$ junctions, a phosphorus-doped $n$-type layer was formed on (001)-oriented boron-doped $ p$-type one by applying an optimized homoepitaxial growth technique based on micro-wave plasma-enhanced chemical vapor deposition. Current–voltage characteristics showed a rectification ratio of $10^{6}$ at $\pm 30$ V at room temperature. The existence of the space-charge layer through the $ p$–$n$ junction was confirmed from capacitance–voltage characteristics. A strong UV light emission at 235 nm was observed at forward current over 20 mA and is attributed to free exciton recombination.
