Witrynac in the newly discovered Cr-based superconductor K 2Cr 3As 3. The resistivity measurements show that the crystals prepared using high-purity Cr metal (99.99%) have an electron mean free path much larger than the superconducting coherence length. For the crystals prepared using impure Cr that contains various non-magnetic … WitrynaConcentrations of impurities are presented in ppmw (parts per million by weight), 1 ppmw corresponds to 10-4% by weight. The following reagents were used potassium dihydrogen phosphate, phosphoric acid and potassium hydroxide with Al, Cr, Fe and Ti impurities content of <0.5 ppmw.
Witryna23 lut 2024 · It is found that electronic temperature (T e) and chemical potential (μ) decrease faster with the increase in the Cr doping concentration. Similarly, the lifetime (τ) of the excited electrons also decreases with more Cr doped into Bi 2 Se 3.
