This could probably be implemented in Silicon using an scanning tunneling microscope to pop off Hydrogen atoms from an H-terminated Silicon surface ([[Patterned Atomic Layer Epitaxy]]), then filling the chamber with something like Fluorine radicals, or some other molecule that will deposit a Fluorine or Chlorine atom on the depassivated spots. Hydrogen is 0, the other element is 1. Then it could be read it with an atomic force microscope, as demonstrated by Oscar Custance and company in [http://www.nature.com/nature/journal/v446/n7131/edsumm/e070301-01.html "Chemical identification of individual surface atoms by atomic force microscopy"] Nature, March 2007. | This could probably be implemented in Silicon using an scanning tunneling microscope to pop off Hydrogen atoms from an H-terminated Silicon surface ([[Patterned Atomic Layer Epitaxy]]), then filling the chamber with something like Fluorine radicals, or some other molecule that will deposit a Fluorine or Chlorine atom on the depassivated spots.
