We have developed a GaN-based distributed feedback laser diode (DFB-LD) with the detuning of +5 nm to obtain a smaller temperature dependence of the threshold current. We found that the current-light characteristics almost overlapped up to 300 mW bet

The crystal growth and optical properties of semipolar (112¯2) InGaN/AlGaN stress-compensated superlattices (SCSLs) are investigated. X-ray diffraction and transmission electron microscopy reveal that appropriately designed 125-period In0.2Ga0.8N (1

We investigated the surface morphologies of nonpolar m-plane AlN homoepitaxial layers grown by the flow-rate modulation epitaxy (FME) method. As source supply sequences, we adopted conventional metal-organic chemical vapor deposition (MOCVD) and thre

We designed and fabricated lateral-current-injection (LCI) Fabry-Perot (FP) lasers for the 1.3-µm wavelength region. The devices were fabricated using selective doping by means of thermal diffusion and ion implantation to make pn junctions. To incre

We studied hole generation in Mg-doped AlN/Al0.75Ga0.25N superlattices (SLs) with an average Al content of 0.8. High hole concentrations on the order of 1018 cm−3 were obtained in the SLs. The temperature dependence of the hole concentration indica

We investigate the surface morphologies of nonpolar m-plane AlN homoepitaxial layers grown by flow-rate modulation epitaxy (FME). As source supply sequences, we employ a continuous supply and three types of FME: group-III-source FME, group-V-source F

We investigate anisotropic lattice relaxation in non-c-plane InGaN/GaN multiple quantum wells(MQWs).Transmission electron microscopy analyses of semipolar (11{2¯}2)MQWs reveal that lattice relaxation preferentially occurs along the [{1¯}{1¯}23] di

We compare metalorganic vapor phase epitaxy of InGaN/GaN heterostructures on semipolar (112¯2) and (1¯1¯22¯) GaN bulk substrates. In incorporation efficiency is higher for (112¯2) InGaN, which enables higher temperature growth of InGaN and is be
