Figure 2: Heating heat flow curves of Ge22Se78 glasses quenched from various cooling rates, −1, −2.5, −5, −10, and −20 K/min across glass transition (from top).
From: Relaxation dynamics in the strong chalcogenide glass-former of Ge22Se78

The heating rates are fixed to be 20 K/min. (a) The sample with the synthesis time of 24 + 10 hours before quenching into ice water; (b) The sample with the synthesis time of 24 + 168 hours.
