Material Physics, Nanoscale Physics and Nanotechnology

Oral presentaion

The development of a high power and high energy density supercapacitor would enable a technology for future space missions due to the need of ultra-lightweight devices, relatively high energy, and high power density with multiple charging cycles. This gives rise to the nanostructured supercapacitors that could provide an operational regime that enhances current technology for making such sorts...

Material Physics, Nanoscale Physics and Nanotechnology

Oral presentaion

This study aims to develop a new method for capacitive improvement of 2 black (2B) (74% graphite, 20% clay and 5% wax; diameter 2.0 mm [1]) pencil graphitic rod through nitric acid treatment followed by CuO deposition via electrochemistry. After acid treatment, oxygen- and nitrogen- containing species were generated on the PR surface, which confirms by x-ray photoelectron spectroscopy (XPS),...

154. Raman Spectroscopy of GaN films on (001)- and (110)-oriented GaAs substrates

Mr Pitshaya Praigaew (Chulalongkorn University)

Magnetic and Semiconductor Physics

Oral presentaion

Structural phases in the GaN films grown on the (001)- and (110)-oriented GaAs substrates were investigated by μ-Raman spectroscopy with the excitation wavelengths of 473, 532 and 633 nm. Raman spectra show a significant shift of phonon modes between the films on the (001)- and (110)-oriented substrates. For the films on the (001)-oriented substrates, phonon mode of cubic-TO was clearly...

199. Magnetic Track Width Modeling

Dr Sujin Suwanna (Department of Physics, Faculty of Science, Mahidol University, Phayathai, Bangkok)

Magnetic and Semiconductor Physics

Oral presentaion

We perform lapping experiments on magnetic readers’ and writers’ heads to determine the relationship between the magnetic track width and the electrical lapping guides, used as sensors to control the writer’s and reader’s lapping process. The experimental results are used to construct the model calibration curve and calculate the magnetic track width sensitivity function, defined as the rate...
