Fig. 3: Shape change and thermosalient behavior.

From: Unraveling two distinct polymorph transition mechanisms in one n-type single crystal for dynamic electronics

Fig. 3

a Crystal shape change associated with the I-II transition and b associated in plane unit cell change accounting for the change in crystal length along the b axis of the unit cell (unit cell drawn in the same orientation as the crystal in (a)). c The resulting thermosalient effect in larger crystals caused by the shape change. d Crystal expansion observed in the II-III transition, compared to (e) the unit cell changes, where the unit cell is shown in the same orientation as the crystal in (d)), and observation of (f) birefringence showing multiple domain formation under polarized optical microscopy.
