Observation of Kondo condensation in a degenerately doped silicon metal
H. Im, D. U. Lee, Y. Jo +10
When a magnetic moment is embedded in a metal, it captures itinerant electrons to form the Kondo cloud1,2, which can spread out over a few micrometres3,4. For a metal with dense ma…
Resonantly pumped bright-triplet exciton lasing in caesium lead bromide perovskites
Guanhua Ying, Tristan Farrow, Atanu Jana +9
The surprising recent observation of highly emissive triplet-states in lead halide perovskites accounts for their orders-of-magnitude brighter optical signals and high quantum effi…
Electrical Modulation of Superconducting Critical Temperature in Liquid-Gated Thin Niobium Films
Jiman Choi, Pradheesh R., Hyungsang Kim +3
We demonstrate that the superconducting critical temperature (Tc) of thin niobium films can be electrically modulated in a liquid-gated geometry device. Tc can be suppressed and en…
Charge transport through ultrasmall single and double Josephson junctions coupled to resonant modes of the electromagnetic environment
Yu. A. Pashkin, H. Im, J. Leppäkangas +5
We have investigated charge transport in ultrasmall superconducting single and double Josephson junctions coupled to resonant modes of the electromagnetic environment. We observe p…
Specific heat study of Ga1-xMnxAs
Sh. U. Yuldashev, Kh. T. Igamberdiev, Sejoon Lee +5
Specific heat measurements were used to study the magnetic phase transition in Ga1-xMnxAs. Two different types of Ga1-xMnxAs samples have been investigated. The sample with a Mn co…
Detection of mechanical resonance of a single-electron transistor by direct current
Yu. A. Pashkin, T. F. Li, J. P. Pekola +6
We have suspended an Al based single-electron transistor whose island can resonate freely between the source and drain leads forming the clamps. In addition to the regular side gat…
