SiGe quantum wells with oscillating Ge concentrations for quantum dot qubits
Thomas McJunkin, Benjamin Harpt, Yi Feng +10
Large-scale arrays of quantum-dot spin qubits in Si/SiGe quantum wells require large or tunable energy splittings of the valley states associated with degenerate conduction band mi…
A Simple Numerical Method for Evaluating Heat Dissipation from Curved Wires with Periodic Applied Heating
Gabriel R. Jaffe, Victor W. Brar, Max G. Lagally +1
In many situations, the dual-purpose heater/thermometer wires used in the three-omega method, one of the most precise and sensitive techniques for measuring the thermal conductivit…
Toward Robust Autotuning of Noisy Quantum Dot Devices
Joshua Ziegler, Thomas McJunkin, E. S. Joseph +7
The current autotuning approaches for quantum dot (QD) devices, while showing some success, lack an assessment of data reliability. This leads to unexpected failures when noisy or…
Valley splittings in Si/SiGe quantum dots with a germanium spike in the silicon well
Thomas McJunkin, E. R. MacQuarrie, Leah Tom +11
Silicon-germanium heterostructures have successfully hosted quantum dot qubits, but the intrinsic near-degeneracy of the two lowest valley states poses an obstacle to high fidelity…
Long Phonon Mean Free Paths Observed in Cross-plane Thermal-Conductivity Measurements of Exfoliated Hexagonal Boron Nitride
Gabriel R. Jaffe, Keenan J. Smith, Kenji Watanabe +4
Sub-micron-thick layers of hexagonal boron nitride (hBN) exhibit high in-plane thermal conductivity, useful optical properties, and serve as dielectric encapsulation layers with lo…
Three-Omega Thermal-Conductivity Measurements with Curved Heater Geometries
Gabriel R. Jaffe, Keenan J. Smith, Victor W. Brar +2
The three-omega method, a powerful technique to measure the thermal conductivity of nanometer-thick films and the interfaces between them, has historically employed straight conduc…
