1. 1. Time-resolved detection of temporally correlated, single-charge tunnelling

   Författare :Jonas Bylander; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Josephson junctions; time-correlated tunnelling; radio-frequency single-electron transistor; current standard; charge solitons; SET oscillations; Coulomb blockade; metrology; SET; tunnel junction array;

   Sammanfattning : We report real-time detection of the single charges that constitute a small electrical current, as they flow through a nano-electronic device. This represents a direct demonstration of charge discreteness in an electrical current. LÄS MER

3. 2. Current measurement by real-time counting of single charges

   Författare :Jonas Bylander; Chalmers tekniska högskola; []

   Sammanfattning : The first real-time observation of time correlated single-electron tunnelling is reported in this thesis. This is a direct detection of charge discreteness in an electrical current.When a current, I, flows through a chain of metallic islands, connected by small tunnel junctions, a lattice of charges is formed due to the Coulomb repulsion.
