Abstract
Amorphous Pd81Si19 is studied by scanning tunneling microscopy before and after crystallization, and after additional laser-quenching. Dista nces between structural units on the amorphous surface are comparable to lattice spacings on the crystallized sample indicating partial pres ervation of the local structure during the phase transformation. After laser-quenching the crystallized sample, the surface structure is sim ilar to that of the initial amorphous state proving on the nm scale th e successful transformation of the surface layers back into the amorph ous state.
