FIG. 1.

(Color online) Total structure factors of crystal , liquid , and amorphous and crystal , liquid , and amorphous GeTe (a). Black lines and red lines represent the experimental data and the best-fitted result of the RMC simulation data, respectively. Total correlation functions of crystal (black), liquid (blue), and amorphous (red) and GeTe (b).

FIG. 2.

(Color online) Ring size distribution in and GeTe (a). Black, red, and blue bars represent the distribution in the crystals, amorphous (obtained by RMC simulation started with NaCl-type structure) and amorphous (obtained by RMC simulation started with random structure), respectively. A atomic configuration and enlarged framework atomic configuration of and obtained from the RMC snapshot (b). The Ge(Sb)–Te and Ge–Ge bonds shorter than 3.4 and are indicated by the sticks, respectively. The red-colored bond represents the Ge–Ge bond.

FIG. 3.

(Color online) Schematic presentation for the possible ring size transformation in crystal-liquid-amorphous phase change (record) and amorphous-crystal phase change (erase) in and GeTe. The red-colored bond represents the Ge–Ge bond. Stage I and II: recording process and stage III: erasing process.
