Operasi gelombang berterusan pada suhu bilik telah ditunjukkan untuk diod laser (LDs) multi-kuantum-well (MQW) InGaN yang ditanam pada substrat FIELO GaN dengan sentuhan n bahagian belakang. Ini dimungkinkan dengan memperkenalkan konsep baharu yang penting untuk mengurangkan kehelan benang yang berlaku semasa pertumbuhan substrat GaN. Kami mendapati bahawa lapisan aktif InGaN yang ditanam pada FIELO GaN adalah lebih baik daripada yang ditanam pada substrat nilam konvensional dari segi mod pertumbuhannya dan hasil turun naik komposisi. Diod laser yang dibuat menunjukkan arus ambang, ketumpatan arus ambang dan voltan ambang adalah 36 mA, 5.4 kA/cm2 dan 7.5 V, masing-masing, dengan panjang gelombang pengelasan 412 nm dan kecekapan kuantum dalaman setinggi 98%.

Abstract: Continuous-wave operation at room-tempera-ture has been demonstrated for InGaN multi-quantum-well (MQW) laser diodes (LDs) grown on FIELO GaN substrates with a backside n-contact. This was made possible by introducing important new concept of reducing threading dislocations that occur during the growth of the GaN substrates. We found that InGaN active layers grown on FIELO GaN are superior to those grown on conventional sapphire substrates in terms of their growth mode and the resultant In compositional fluctuation. The fabricated laser diode shows the threshold current, the threshold current density and the threshold voltage were 36 mA, 5.4 kA/cm2 and 7.5 V, respectively, with the lasing wavelength of 412 nm and internal quantum efficiency as high as 98%.
