Fig. 4: Crystal growth velocity and nucleation rate.
From: Recipe for ultrafast and persistent phase-change memory materials
a Crystal growth velocities U of ScxSb2Te3 and Ge2Sb2Te5 supercooled liquids between Tg and Tm. The maximum velocity Umax value of each material is also shown near the corresponding peak. As the Sc content increases, the peak becomes shorter and shifts to higher temperatures. b Steady-state nucleation rate Iss of Ge2Sb2Te5 (homogeneous, abbreviated as Homo.) and ScxSb2Te3 (heterogeneous, abbreviated as Hetero.) with a contact angle θ of 20° taking the size effect into account.
