In a modern hard disk drive (HDD), when the spacing between slider and disk is on the order of 1 or 2 nm, the gaseous rarefaction effects, surface roughness, and surface accommodation effects must be taken into account. Effects of gaseous rarefaction with either surface roughness or surface accommodation were reported in literature. However, only a few of the published works have considered the combined...
SiNx-doped Sb2Te3 films for nonvolatile memories were prepared by co-sputtering with Si3N4 and Sb2Te3 alloy targets. Electrical and structural properties were investigated and compared to those of conventional GST and pure Sb2Te3 film by annealing temperature-dependent resistivity measurement, x-ray diffraction (XRD). The resistivity ratio is larger than 105 during the phase transition, accompanied...
