Invited Speaker / Conférencier invité
Intensive study of strongly correlated electronic systems has revealed the existence of quantum phase transitions from ordered states to disordered states driven by non-thermal control parameters such as chemical doping, pressure, and magnetic field. In this presentation I will discuss a recent progress of magnetic field-tuned quantum criticality with particular emphasis on the Fermi liquid...

This work aims to develop Ge:Mn dilute magnetic semiconductor and study the fundamental origin of ferromagnetism in this system. Using ion implantation at $77$ K, a single crystal Ge wafer was doped with magnetic Mn ions. The implantation was done at ion energy of $4.76$ MeV with a fluence of 2 x 10$^{16}$ ion/cm$^2$. X-ray diffraction (XRD) of the as-implanted sample showed that the implanted...

Ytterbium-doped yttrium oxide thin films were obtained with a variant of pulsed laser deposition, called reactive crossed-beam laser deposition, wherein a cross-flow of oxygen, synchronized with the laser pulses, is used for oxidizing and entraining the ablation products of a Yb/Y alloy target towards a substrate placed inside a vacuum chamber [1]. The nanostructure of the films is examined...

Incorporation of Bismuth into GaAs causes an anomalous bandgap reduction (88 meV/%
for dilute alloys) with rather small lattice mismatch compared to ternary In or Sb alloys. The bandgap can be adjusted over a wide range of infrared wavelengths up to 2.5 μm by controlling the Bi content of the alloy which is useful for laser, detector and solar cell applications.
Semiconductor lasers are...

Hydrogen terminated silicon (100) $2 \times 1$ (H:Si(100)) is examined using a novel non-contact atomic force microscopy (NC-AFM) approach. NC-AFM gives access to unique information on the surface such as unperturbed surface charge distributions, chemical bonding, and surface forces.
H:Si(100) is an attractive surface for examination due to its potential for nano-electronics. Dangling...
