Graphene quantum dots: In the crossroad of graphene, quantum dots and carbogenic nanoparticles

Structural and Optical Characterization of ZnO-Graphene Nanocomposite Quantum Dots

In this research, zinc oxide quantum dots and graphene nanocomposites were synthesized via two different methods; In the first (direct) method, ZnO-graphene Nanocomposites were made mixing the synthesized zinc oxide and graphene. In the second (indirect) method, zinc nitrate, graphene, and sodium hydroxide were used to made ZnO-graphene Nanocomposites. XRD, FTIR and Raman spectroscopy analyses ...

Quantum Dots in Graphene

The paper reports on theoretical study of electron states for a quantum dot in a graphene monolayer. Discrete energy spectrum of quasiparticles inside the quantum dot is found. Energy levels and corresponding quasiparticle resonant wave functions are obtained, which allow calculating the local density of states inside the quantum dot. Some experimental results recently released are referred.

Graphene based quantum dots.

Laterally localized electronic states are identified on a single layer of graphene on ruthenium by low temperature scanning tunneling spectroscopy (STS). The individual states are separated by 3 nm and comprise regions of about 90 carbon atoms. This constitutes a highly regular quantum dot-array with molecular precision. It is evidenced by quantum well resonances (QWRs) with energies that relat...

Quantum Transport in Graphene Quantum Dots

Quantum Dots and Andreev Reflections in Graphene Quantum Dots and Andreev Reflections in Graphene

Preface By the end of my Master's thesis in University of Groningen in 2006, I was convinced that I wanted to do a PhD working on cold atoms. However, Marius Costache, who was at that moment a PhD student in Groningen, urged me to apply also to the quantum transport group (QT) in Delft. So I did. During my interview in Delft, QT people impressed me for being exceptionally smart and at the same ...
