Observation of room-temperature negative differential resistance in Gd-doped Si nanowires on Si(110) surface
{{output}}
The massively parallel arrays of highly periodic Gd-doped Si nanowires (SiNWs) self-organized on Si(110)-16 × 2 surface were investigated by scanning tunneling microscopy and spectroscopy. These periodic Gd-doped SiNWs are atomically precise and show equal si... ...
