Switching Mechanism

Abstract It is important to understand the switching mechanism of phase change material for failure analysis of PRAM device. In this study, the real time observations of phase transition and void formation mechanism of confined GST structure were investigated using in-situ TEM with multi-pulse AC biasing technique. In-situ SET switching behavior between amorphous state and crystalline state with continuous structural change was successfully observed. Volume shrink of GST, due to the phase transition, induced voids at grain boundary of crystalline phase. Excess Joule-heating after crystallization caused coalescence and migration of voids. These results may give us a crucial clue for endurance failure analysis of PRAM.

The integration of ferroic oxide thin films into advanced flexible electronics will bring multifunctionality beyond organic and metallic materials. However, it is challenging to achieve high flexibility in single-crystalline ferroic oxides that is considerable to organic or metallic materials. Here, we demonstrate the superior flexibility of freestanding single-crystalline BiFeO3 membranes, which are typical multiferroic materials with multifunctionality. They can endure cyclic 180° folding and have good recoverability, with the maximum bending strain up to 5.42% during in situ bending under scanning electron microscopy, far beyond their bulk counterparts. Such superior elasticity mainly originates from reversible rhombohedral-tetragonal phase transition, as revealed by phase-field simulations. This study suggests a general fundamental mechanism for a variety of ferroic oxides to achieve high flexibility and to work as smart materials in flexible electronics.
