This week our image comes from L Persichetti et al who explore the controversial and heavily disputed structural transformation in Ge (0 0 1).
In their paper, they use scanning tunneling microscopy to study the phase transition of Ge (0 0 1) in order to better understand the complex nanscopic mechanisms at play.
Large-scale STM images of the nominal Ge(0 0 1) surface after few seconds flash annealing to 1170 K. L Persichetti et al 2015 J. Phys.: Condens. Matter 27 435001.
To find out what drives the phase transition in Ge (0 0 1); dimer breakup or step/ domain wall proliferation, you can read the full results here.
