Cyclotron resonance of high-mobility GaAs/AlGaAs (311) 2DHGs

Anomalous magnetotransport and cyclotron resonance of high mobility magnetic 2DHGs in the quantum Hall regime

Low temperature magnetotransport measurements and far infrared transmission spectroscopy are reported in molecular beam epitaxial grown twodimensional hole systems confined in strained InAs quantum wells with magnetic impurities in the channel. The interactions of the free holes spin with the magnetic moment of 5/2 provided by manganese features intriguing localization phenomena and anomalies i...

High-resolution ion cyclotron mobility spectrometry.

A novel ion mobility spectrometry instrument incorporating a cyclotron geometry drift tube is presented. The drift tube consists of eight regions, four curved drift tubes and four ion funnels. Packets of ions are propagated around the drift tube by changing the drift field at a frequency that is resonant with the ion's drift time through each region. The approach trims each packet of ions as it...

Cyclotron Resonance in High Magnetic Fields

We review recent cyclotron resonance studies of semiconductors performed in high magnetic fields. This traditional semiconductor characterization method has been used to study some of the recentlydeveloped materials systems, including ferromagnetic III-V semiconductors and two-dimensional electron gases formed in InSb/InAlSb and GaN/AlGaN heterostructures. These studies have not only provided a...

Cyclotron Resonance and Quasiparticles

This introductory paper contains personal perspectives about the importance of cyclotron resonance in forming our modern view of solids. The papers following this one will discuss the discovery, refinements, and some of the latest developments. Although I will touch on some of these subjects, I leave the details to the other authors and in the main focus on the conceptual impact of the work. I ...
