Fig. 2: Manipulation and interconversion of polarons.
From: Manipulating single excess electrons in monolayer transition metal dihalide

a, b STM images showing erasing and creating a type-I (down) polaron. c, d STM images showing moving a type-I (down) polaron. e, f STM images showing interconversion between type-I (down) and type-I (up) polarons. The red dashed circles mark the original location of the polarons before manipulation. The red arrows mark the manipulated polarons.
