The ECR ion source (ECRIS) is still an active field of research and development, as demonstrated by the numerous contributions to the ECRIS’12 workshop and ICIS’13 conference. It is impossible to present all the interesting ECR development in this paper. Instead, a selection of ECR development for linear accelerator and synchrotrons are presented along with some original recent ECR contribution...

We present a theory for the electronic and optical properties of nand p-type In1−xMnxAs in ultra-high magnetic fields. An eight-band effective mass model based on the Pidgeon–Brown model and including the wavevector dependence of the electronic states as well as the s–d and p–d exchange interactions with Mn d-electrons is used to determine the electronic states. The optical properties such as c...

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...
