Report

Single-shot readout of the nuclear spin of an on-surface atom

Autor: Stolte, Evert W., Lee, Jinwon, Vennema, Hester G., Broekhoven, Rik, Teng, Esther, Katan, Allard J., Veldman, Lukas M., Willke, Philip, Otte, Sander

Nuclear spins owe their long-lived magnetic states to their excellent isolation from the environment. At the same time, a finite degree of interaction with their surroundings is necessary for reading and writing the spin state. Therefore, detailed kn

Report

Single-Molecule Structure and Topology of Kinetoplast DNA Networks

Autor: He, Pinyao, Katan, Allard J., Tubiana, Luca, Dekker, Cees, Michieletto, Davide

The Kinetoplast DNA (kDNA) is a two-dimensional Olympic-ring-like network of mutually linked 2.5 kb-long DNA minicircles found in certain parasites called Trypanosomes. Understanding the self-assembly and replication of this structure are not only ma

Report

Semi-permeability of graphene nanodrums in sucrose solution

Autor: Dolleman, Robin J., Katan, Allard J., van der Zant, Herre S. J., Steeneken, Peter G.

Semi-permeable membranes are important elements in water purification and energy generation applications, for which the atomic thickness and strength of graphene can enhance efficiency and permeation rate while maintaining good selectivity. Here, we

Report

Local electrodynamics of a disordered conductor model system measured with a microwave impedance microscope

Autor: Thierschmann, Holger, Cetinay, Hale, Finkel, Matvey, Katan, Allard J., Westig, Marc P., Van Mieghem, Piet, Klapwijk, Teun M.

Publikováno v: Phys. Rev. Applied 13, 014039 (2020)

We study the electrodynamic impedance of percolating conductors with a pre-defined network topology using a scanning microwave impedance microscope (sMIM) at GHz frequencies. For a given percolation number we observe strong spatial variations across

Report

Shielded cantilever with on-chip interferometer circuit for THz scanning probe impedance microscopy

Autor: Finkel, Matvey, Thierschmann, Holger, Katan, Allard J., Westig, Marc P., Spirito, Marco, Klapwijk, Teun M.

Publikováno v: Rev. Sci. Inst. 90, 113701 (2019)

We have realized a microstrip based THz near field cantilever which enables quantitative measurements of the impedance of the probe tip at THz frequencies (0.3 THz). A key feature is the on-chip balanced hybrid coupler which serves as an interferomet

Report

Spatial conductivity mapping of unprotected and capped black phosphorus using microwave microscopy

Autor: de Visser, Pieter J., Chua, Rebekah, Island, Joshua O., Finkel, Matvey, Katan, Allard J., Thierschmann, Holger, van der Zant, Herre S. J., Klapwijk, Teun M.

Publikováno v: 2D Materials 3, 021002 (2016)

Thin layers of black phosphorus present an ideal combination of a 2D material with a tunable direct bandgap and high carrier mobility. However the material suffers from degradation in ambient conditions due to an oxidation reaction which involves wat
