December 2020 – We present a first detailed study of the charge density wave (CDW) contrast inversion in scanning tunneling microscopy (STM) images. Combining high resolution STM imaging at different tunneling biases and density functional theory, we demonstrate that contrast inversion is very sensitive to the position of the CDW gap with respect to the…

September 2020 – Congratulations to Tim Gazdic who successfully defended his PhD thesis on September 8, 2020. He performed a range of beautiful scanning tunneling microscopy and spectroscopy studies of highly overdoped Bi-2212. Among the key findings is a strong charge-order like reconstruction which is actually due to quasi-particle interferences. He also observes for the…
