Extended Data Fig. 2: TEM image of the SiTex filament in the set state.

From: Phase-change memory via a phase-changeable self-confined nano-filament

Extended Data Fig. 2

High-resolution TEM image of the set state device with the aggressive forming process. The image shows lattice fringes in the filament while showing amorphous (no lattice fringes) in the a-Si region. The high-resolution TEM image indicates the formation of poly-crystalline SiTex filament in the set state.
