Enhanced mobility of ternary InGaAs quantum wells through digital alloying
Jason T. Dong, Yilmaz Gul, Aaron N. Engel +4
High In content InGaAs quantum wells (In 75%) are potentially useful for topological quantum computing and spintronics applications. In high mobility InGaAs quantum wells, a…
Spin-orbit coupling in digital alloyed InGaAs quantum wells
Jason T. Dong, Yilmaz Gul, Irene Villar Rodriguez +5
Increasing the spin-orbit coupling in InGaAs quantum wells is desirable for applications involving spintronics and topological quantum computing. Digital alloying is an approach to…
Many-body effects in a quasi-one-dimensional electron gas
Sanjeev Kumar, Kalarikad J. Thomas, Luke W. Smith +6
We have investigated electron transport in a quasi-one dimensional (quasi-1D) electron gas as a function of the confinement potential. At a particular potential configuration, and…
Thermoelectric property of a one dimensional channel in the presence of a transverse magnetic field
Chengyu Yan, Michael Pepper, Patrick See +3
We studied the thermal conduction through a quantum point contact (QPC), defined in GaAs-AlGaAs heterostructure, in the presence of a transverse magnetic field. A shift in the posi…
'Metal'-like transport in high-resistance, high aspect ratio two-dimensional electron gases
Dirk Backes, Richard Hall, Michael Pepper +3
We investigate the striking absence of strong localisation observed in mesoscopic two-dimensional electron gases (2DEGs) (Baenninger et al 2008 Phys. Rev. Lett. 100 1016805, Backes…
Demonstration of electron focusing using electronic lenses in low-dimensional system
Chengyu Yan, Michael Pepper, Patrick See +3
We report an all-electric integrable electron focusing lens in n-type GaAs. It is shown that a pronounced focusing peak takes place when the focal point aligns with an on-chip dete…
