Quantum dots in carbon nanotubes
In this overview paper, we present low-temperature electronic transport measurements of carbon nanotube quantum dots with a back gate. In a semiconducting tube, charge carriers could be completely depleted. The addition energy and the excitation spectrum have been studied as a function of the number of charges (electrons or holes), one by one. We observe electron–hole symmetry, which is a direc...
متن کاملPhonon runaway in carbon nanotube quantum dots
Phonon runaway in carbon nanotube quantum dots" (2008). Other Nanotechnology Publications. Paper 93. We explore electronic transport in a nanotube quantum dot strongly coupled with vibrations and weakly with leads and the thermal environment. We show that the recent observation of anomalous conductance signatures in single-walled carbon nanotube quantum dots ͓B. can be understood quantitatively ...
متن کاملCarbon Quantum Dots for Zebrafish Fluorescence Imaging
Carbon quantum dots (C-QDs) are becoming a desirable alternative to metal-based QDs and dye probes owing to their high biocompatibility, low toxicity, ease of preparation, and unique photophysical properties. Herein, we describe fluorescence bioimaging of zebrafish using C-QDs as probe in terms of the preparation of C-QDs, zebrafish husbandry, embryo harvesting, and introduction of C-QDs into e...
متن کاملCotunneling renormalization in carbon nanotube quantum dots
We determine the level shifts induced by cotunneling in a Coulomb blockaded carbon nanotube quantum dot using leading-order quasidegenerate perturbation theory within a single nanotube “shell.” It is demonstrated that otherwise degenerate and equally tunnel coupled K and K ′ states are mixed by cotunneling and therefore split up in energy except at the particle-hole-symmetric midpoints of the C...
