The challenges in designing future head disk interface (HDI) demand efficient theoretical modeling tools with flexibility in investigating various combinations of perfluoropolyether (PFPE) and carbon overcoat (COC) materials. For broad range of time

During the intermittent contact between the head and the disk of the hard disk drive (HDD), the perfluoropolyether (PFPE) lubricant experiences shear/elongation deformation. Therefore, the molecular rheology of PFPE becomes critically important in de

Molecularly thin perfluoropolyether (PFPE) has been used extensively as a high-performance lubricant in various applications and, more importantly, on carbon overcoats to enhance the reliability and lubrication of micro-/nanoelectro-mechanical system

Accurate estimation of surface wettability for various degrees of hydrophobicity becomes increasingly important in the molecular design of membrane. In this paper, we develop simple yet physically realistic model for estimating contact angle via hybr

Due to the nanoscale dimensions of the lubricant, overcoat, and media layers, the usual fast and efficient continuum models, such as Fourier law, fail to describe the thermal effects occurring during the heat-assisted magnetic recording (HAMR) operat

As the head-media spacing of head-disk interface (HDI) is reduced to 7 nm, interfacial configurations of molecularly thin perfluoropolyether (PFPE) lubricant film such as surface morphology and film conformation become critical for the stability of h

Increasing magnetic recording density requires reduction in head-media spacing (HMS) down to 7 nm and introduction of new recording techniques (e.g., heat-assisted magnetic recording). Future head-disk interface (HDI) configuration demands stable pro

Heat-assisted magnetic recording (HAMR) is one of the most promising techniques to extend the recording density in hard disk drives beyond 4 Tb/in 2 . This places a range of stringent operating requirements in the head disk interface, including heati

Graphene has unique mechanical properties in that it is simultaneously very strong and stretchy, which severely hampers the prediction of its orientation-dependent fracture behavior based on conventional theories used for common brittle or ductile ma
