Abstract: A single crystalline InAlGaN film is successfully grown on a sapphire substrate by radio-frequency plasma-excited molecular beam epitaxy.The streaky RHEED pattern observed during growth indicates a layer-by-layer growth mode.Rutherford backscattering spectrometry (RBS) shows that the In,Al,and Ga contents in the InAlGaN film are 2%,22%,and 76%, respectively.Triple-axis X-ray diffraction shows that the full width at half maximum of the InAlGaN (0002) peak is 4.8′.There are some mountain-like hillocks and pits on the surface of the InAlGaN film.Atomic-force microscopy shows that the RMS of the InAlGaN film is 2.2nm.Photoconductance measurements show that the energy gap of InAlGaN film is 3.76eV.

Key words: RF-MBE InAlGaN RHEED XRD AFM
