Resistance in sub-m size GaAs lines
Artikel i vetenskaplig tidskrift, 1987

The electrical resistance in GaAs submicron mesa lines has been studied as a function of the line width. Using molecular beam epitaxy two types of conducting layers were made: an n+-layer and a two-dimensional electron gas confined to an (AlGa)As/GaAs heterostructure. Processing of the lines was made by photolithography, electron beam lithography and ion etching. Resistance data at 77 K and 300 K are discussed for line widths in the interval 0.2 to 5 m. A size dependent conduction was found and interpreted in terms of geometry induced limitation of the effective conducting path
