Development of an ultrasonic experimental device to characterise concrete for structural repair

Farouk Benmeddour, Géraldine Villain, Odile Abraham, Marta Choinska

Various non-destructive testing methods, based on the propagation of ultrasonic waves, can be used to characterise the mechanical properties of structural concrete in situ. The results obtained however are heavily influenced by both water content and concrete mix design. To overcome these biases,...

Loosening quantum confinement : observation of real conductivity caused by hole polarons in semiconductor nanocrystals smaller than the Bohr radius

Ronald Ulbricht, Joep J. H. Pijpers, Esther Groeneveld, Rolf Koole, Celso de Mello Donega, Daniel Vanmaekelbergh, Christophe Delerue, Guy Allan, Mischa Bonn

We report on the gradual evolution of the conductivity of spherical CdTe nanocrystals of increasing size from the regime of strong quantum confinement with truly discrete energy levels to the regime of weak confinement with closely spaced hole states. We use the high-frequency (terahertz) real and...
