Measurement of phosphorus segregation in silicon at the atomic scale using scanning tunneling microscopy

Measurement of phosphorus segregation in silicon at the atomic scale using scanning tunneling microscopy

In order to fabricate precise atomic-scale devices in silicon using a combination of scanning tunnelling microscopy (STM) and molecular beam epitaxy it is necessary to minimize the segregation/diffusion of dopant atoms during silicon encapsulation. We characterize the surface segregation/diffusion of phosphorus atoms from a $\delta$-doped layer in silicon after encapsulation …
