We have measured the differential conductance of a parallel carbon nanotube (CNT) double quantum dot (DQD) with strong inter‐dot capacitance and inter‐dot tunnel coupling. Nominally, the device consists of a single CNT with two contacts. However, we identify two sets of Coulomb blockade (CB) diamonds that do not block transport individually, which suggest that two quantum dots (QDs) are contacted in parallel. We find strong and periodic anti‐crossings in the gate and bias dependence, which are… 
Parallel-Coupled Quantum Dots in InAs Nanowires.
The combination of hard-wall barriers to source and drain, shallow interdot tunnel barriers, and very high single-particle excitation energies allow an order of magnitude tuning of the strength for the first intramolecular bond.

This thesis explores crystal-phase engineering of nanowires to fabricate advanced quantum structures for charge and spin transport studies. Quantum dots formed by crystal-phase tuning during
Effective theory of monolayer TMDC double quantum dots
Monolayer transition metal dichalcogenides (TMDCs) are promising candidates for quantum technologies, such as spin qubits in quantum dots, because they are truly two-dimensional semiconductors with a

Transport spectroscopy of a spin-orbit-coupled spin to a quantum dot
Electron spins in quantum dots can interact with impurity spins located in an adjacent region. This interaction may be controllable using external electric fields and it can involve an appreciable

We present quantum transport measurements of interacting parallel quantum dots formed in the strands of a carbon nanotube rope. In this molecular quantum dot system, transport is dominated by one
Pauli spin blockade in carbon nanotube double quantum dots
We report Pauli spin blockade in a carbon nanotube double quantum dot defined by tunnel barriers at the contacts and a structural defect in the nanotube. We observe a pronounced current suppression
Eightfold shell filling in a double-wall carbon nanotube quantum dot.
It is shown that the observed eightfold shell filling is a unique characteristic of a double-wall carbon nanotube quantum-dot device, which implies an eightfold degeneracy in the single-particle energy levels, which is higher than the fourfold degenerateacy of a single-wallcarbon nanotubes.
Resonant and Inelastic Andreev Tunneling Observed on a Carbon Nanotube Quantum Dot.
Two fundamental subgap transport processes through a quantum dot (QD) with a superconducting contact are observed, with a single resonance with position, shape, and amplitude consistent with the theoretically predicted resonant Andreev tunneling through a single QD level.
Ultraclean single, double, and triple carbon nanotube quantum dots with recessed Re bottom gates.
This work demonstrates that ultraclean single, double, and triple quantum dots (QDs) can be formed reliably in a carbon nanotube (CNT) by a straightforward fabrication technique and opens up a route to more complex devices based on ultracleans CNTs, since it allows for postgrowth processing.

Electron transport in very clean, as-grown suspended carbon nanotubes
The clean transport data show a correlation between the contact junction resistance and the various transport regimes in single-walled-carbon-nanotube devices, and electrical transport data can be used to probe the band structures of nanotubes, including nonlinear band dispersion.
