Raman scattering reveals strong LO-phonon-hole-plasmon coupling in nominally undoped GaAsBi: optical determination of carrier concentration (2014)
Journal Article
Steele, J., Lewis, R., Henini, M., Lemine, O., Fan, D., Mazur, Y., Dorogan, V., Grant, P., Yu, S., & Salamo, G. (2014). Raman scattering reveals strong LO-phonon-hole-plasmon coupling in nominally undoped GaAsBi: optical determination of carrier concentration. Optics Express, 22(10), https://doi.org/10.1364/OE.22.011680

We report room-temperature Raman scattering studies of nominally undoped (100) GaAs1−xBix epitaxial layers exhibiting Biinduced (p-type) longitudinal-optical-plasmon coupled (LOPC) modes for 0.018≤x≤0.048. Redshifts in the GaAs-like optical modes due...

Circular polarization in n-type resonant tunneling diodes with Si delta-doping in the quantum well (2014)
Presentation / Conference Contribution
Herval, L. S., Galeti, H., Orsi Gordo, V., Galvao Gobato, Y., Brasil, M., Taylor, D., & Henini, M. Circular polarization in n-type resonant tunneling diodes with Si delta-doping in the quantum well. Presented at 29th Symposium on Microelectronics Technology and Devices (SBMicro) 2014

In this work, we have investigated magneto-transport and polarization resolved photoluminescence of a GaAs/AlGaAs resonant tunneling diode with Si delta-doping at the center of the quantum well under a magnetic field parallel to the tunnel current. T... Read More about Circular polarization in n-type resonant tunneling diodes with Si delta-doping in the quantum well.

Scanning capacitance imaging of compressible and incompressible quantum Hall effect edge strips (2012)
Journal Article
Suddards, M., Baumgartner, A., Henini, M., & Mellor, C. J. (2012). Scanning capacitance imaging of compressible and incompressible quantum Hall effect edge strips. New Journal of Physics, 14, Article 08315. https://doi.org/10.1088/1367-2630/14/8/083015

We use dynamic scanning capacitance microscopy to image compressible and incompressible strips at the edge of a Hall bar in a two-dimensional electron gas (2DEG) in the quantum Hall effect (QHE) regime. This method gives access to the complex local c... Read More about Scanning capacitance imaging of compressible and incompressible quantum Hall effect edge strips.
