Multi-wall carbon nanotubes as quantum dots [PDF]
Physical Review Letters, 2001 We have measured the differential conductance dI/dV of individual multi-wall carbon nanotubes (MWNT) of different lengths. A cross-over from wire-like (long tubes) to dot-like (short tubes) behavior is observed.

Evolution and Synthesis of Carbon Dots: From Carbon Dots to Carbonized Polymer Dots [PDF]
Advanced Science, 2019 AbstractDespite the various synthesis methods to obtain carbon dots (CDs), the bottom‐up methods are still the most widely administrated route to afford large‐scale and low‐cost synthesis. However, as CDs are developed with increasing reports involved in producing many CDs, the structure and property features have changed enormously compared with the ...

Spin-dependent electronic hybridization in a rope of carbon nanotubes [PDF]
, 2011 We demonstrate single electron addition to different strands of a carbon nanotube rope. Anticrossings of anomalous conductance peaks occur in quantum transport measurements through the parallel quantum dots forming on the individual strands. We determine
