The effective implementation of an etch process in molecular beam epit
axy (MBE) technology is confirmed by reflection high-energy electron d
iffraction (RHEED). Preliminary experimental results obtained on hydro
gen chloride (HCl)-etched GaAs(001) epilayers pointed out the remarkab
le ability to reproducibly fine-tune the etch process down to a single
monolayer (ML) scale under the usual (2 x 4) arsenic-stabilized surfa
ce.
