Abstract:Direct InN growth is demonstrated and characterized on a sapphire (Al2O3) substrate by plasma‐enhanced metal–organic chemical vapor deposition using high‐density nitrogen (N2) microstrip‐line microwave plasma. N2 plasma irradiation at 650 °C for 20 min forms AlN on Al2O3 substrate. No peak regarding metallic In droplets is detected from InN/Al2O3 regardless of N2 plasma irradiation. InN is found to be rotated 30° with their a‐axis oriented to become InN // Al2O3. The transition layers are confirmed at the In… Show more
