Far-infrared probe of size dispersion and population fluctuations in doped self-assembled quantum dots

Isaia, J.; Vaulchier, L.; Hameau, S.; Ferreira, R.; … - In: The European Physical Journal B - Condensed Matter and … 35 (2003) 2, pp. 209-216

We investigate the FIR magneto-optical transitions in doped self-assembled InAs quantum dots with an average filling ranging from 0.6 to 6 electrons per dot. Significant changes in the magnetic field dispersion, the line-width and the amplitude of the transitions are observed as the doping level...

Measurement of the penetration depth λ(T) as a function of temperature using millimeter wave transmission in the range 130-500GHz are reported for three YBa<Subscript>2</Subscript> (YBCO) laser ablated thin films. Two films, deposited on a LaAlO<Subscript>3</Subscript> substrate (T <Subscript> c </Subscript>=90.2 K), exhibit a narrow resistive transition (0.3...</subscript></subscript></subscript>
