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…
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…
How valley-orbit states in silicon quantum dots probe quantum well interfaces
J. P. Dodson, H. Ekmel Ercan, J. Corrigan +7
The energies of valley-orbit states in silicon quantum dots are determined by an as yet poorly understood interplay between interface roughness, orbital confinement, and electron i…
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…
Ray-based framework for state identification in quantum dot devices
Justyna P. Zwolak, Thomas McJunkin, Sandesh S. Kalantre +4
Quantum dots (QDs) defined with electrostatic gates are a leading platform for a scalable quantum computing implementation. However, with increasing numbers of qubits, the complexi…
Magnetic gradient free two axis control of a valley spin qubit in SiGe
Y. -Y. Liu, L. A. Orona, Samuel F. Neyens +3
Spins in SiGe quantum dots are promising candidates for quantum bits but are also challenging due to the valley degeneracy which could potentially cause spin decoherence and weak s…
