"direct-write scanning tunneling microscopy... metal contacts fabricated on individual genomics, nanotechnology and robotics (GNRs) and control their electronic character...  electron beam in precursor STM direct-write trigger metal deposition from hafnium diboride precursor molecules is very precise... done in ultra-high vacuum (UHV). This ensures that the material stays clean from atmospheric water and other "junk" that degrades device performance... scaling microelectronic devices"
