Extremely Narrow Violet Photoluminescence Line from Ultrathin InN Single Quantum Well on Step-Free GaN Surface
An ultrathin (one monolayer thick) InN single quantum well (SQW) formed on a step-free GaN surface shows very sharp violet PL emission. The size (16 mu m in diameter) is large enough for state-of-the-art nanotechnology to handle. Longer wavelength emissions, such as green and red, are expected by increasing the thickness of the SQW through the utilization of the quantum size effect.
