Yellow electroluminescence from sputtering synthesized aluminum nitride nanocomposite thin film containing aluminum nanocrystals

Yang M., Chen T.P., Liu Y., Wong J.I., Nanyang Technological University, SG

In this work, visible electroluminescence (EL) from aluminum nitride (AlN) thin films containing aluminum nanocrystals (nc-Al) prepared by a radio frequency sputtering technique is reported. The yellow EL shows a spectrum peaked at 565 nm. [...]

Instability in flatband votlage of SiO2 embedded with silicon nanocrystals

Ng C.Y., Wong J.I., Yang M., Chen T.P., Nanyang Technological University, SG

In this work, the stability of the flatband voltage due to the Si-ions implantation into the SiO2 and subsequent annealing is being studied. There are lack of study on the impact of different annealing temperature [...]

Static dielectric constant of SiO2 embedded with silicon nanocrystals

Ng C.Y., Yang M., Wong J.I., Chen T.P., Nanyang Technological University, SG

The static dielectric constant of isolated silicon nanocrystal (nc-Si) embedded in a SiO2 thin film synthesized by Si+ implantation has been determined from capacitance measurement based on the Maxwell-Garnett effective medium approximation and the Stopping [...]
