| Summary: | The methods of preparation of the group III nitrides AlN, GaN, and InN by laser ablation (i.e. laser
sputtering), is here reviewed including studies on their properties. The technique, concerns direct ablation
of nitride solid targets by laser to produce a plume which is collected on a substrate. Alternatively nitride
deposition is obtained as a result of laser ablation of the metal and subsequent reaction in an NH3 atmosphere. Optical multichannel emission spectroscopic analysis, and time of flight (TOF) mass spectrometry
have been applied for in situ identification of deposition precursors in the plume moving from the target.
Epitaxial AlN, GaN, and InN thin films on various substrates have been grown. X-ray diffraction, scanning
electron microscopy, have been used to characterise thin films deposited by these methods. |
