Investigation of Mobility Limiting Mechanisms in Undoped Si/SiGe Heterostructures
X. Mi, T. M. Hazard, C. Payette +4
We perform detailed magnetotransport studies on two-dimensional electron gases (2DEGs) formed in undoped Si/SiGe heterostructures in order to identify the electron mobility limitin…
Charge Relaxation in a Single Electron Si/SiGe Double Quantum Dot
K. Wang, C. Payette, Y. Dovzhenko +2
We measure the interdot charge relaxation time T_1 of a single electron trapped in an accumulation mode Si/SiGe double quantum dot. The energy level structure of the charge qubit i…
Single charge sensing and transport in double quantum dots fabricated from commercially grown Si/SiGe heterostructures
C. Payette, K. Wang, P. J. Koppinen +3
We perform quantum Hall measurements on three types of commercially available modulation doped Si/SiGe heterostructures to determine their suitability for depletion gate defined qu…
Gate Adjustable Coherent Three and Four Level Mixing in a Vertical Quantum Dot Molecule
C. Payette, S. Amaha, T. Hatano +6
We study level mixing in the single particle energy spectrum of one of the constituent quantum dots in a vertical double quantum dot by performing magneto-resonant-tunneling spectr…
Two level anti-crossings high up in the single-particle energy spectrum of a quantum dot
C. Payette, D. G. Austing, G. Yu +5
We study the evolution with magnetic field of the single-particle energy levels high up in the energy spectrum of one dot as probed by the ground state of the adjacent dot in a wea…
Magnetic field induced effects in the high source-drain bias current of weakly coupled vertical quantum dot molecules
D. G. Austing, C. Payette, G. Yu +1
We report on the basic properties of recently observed magnetic field resonance, induced time dependent oscillation, and hysteresis effects in the current flowing through two weakl…
