Research Highlights

Cooling effect of thermal actuator in hard disk drives This study developed a method used to study the cooling effect on the thermal actuator of a flying slider with greater sensitivity than magnetoresistive sensor measurements. By monitoring the first and second harmonics of the read back signal associated with the ac excited thermal protrusion, the second harmonic signal diverges from the linear first harmonic signal as cooling effect intensifies.

Mechanical properties of carbon nanotubes This research focuses on using molecular dynamics simulation method to perform computational studies on single- and multi-walled carbon nanotubes. Brenner's "second generation" reactive empirical bond order potential was used to described the interatomic forces. For more information about this research work, please click here.

Thermal actuated sliders in hard disk drives Various studies were performed on thermal actuated sliders in hard disk drives. Thermal actuated sliders help to achieve ultra-low and stable flying height, which are crucial for achieving high areal densities in magnetic recording. Several coupled-field studies were carried out. The physics of the heat transfer process from the slider of a hard disk drive to its disk was also investigated.

Mechanical properties of carbon nanotube bundles This is a continuation study of carbon nanotubes. This study concentrates on the mechanical properties of carbon nanotube bundles as well as twisting effects of carbon nanotubes when they are subjected to axial compression and tension. Brenner's "second generation" reactive empirical bond order potential was used to described the interatomic forces. For more information about this research work, please click here.
