Scanning Probe Microscopy (SPM) techniques (STM, AFM, SNOM…) have allowed the emergence of Nanoscience and Nanotechnology. These fields represent new frontiers to study a variety of physical, chemical and biological phenomena on a scale at least 10000 times smaller than the world we normally observe. The Universidad Autónoma de Madrid, in particular the Department of Condensed Matter Physics, counts with a longstanding tradition in SPM, a group of techniques in continuous evolution among the most versatile and powerful instrumentation to investigate the nanoworld.
In this seminar, I will present my research of the last years on low dimensional systems through the use and development of advanced AFM tools. I will start with a brief introduction on instrumental and methodological contributions to the advancement of nanoscale characterization techniques, including a novel and simple method to fabricate nanoelectrodes by AFM manipulation and assembly of metal nanowires. Then I will comment the work done on tuning graphene properties by applying ultrahigh pressures locally, along with the isolation of antimonene, one of the few elementary 2D allotropes. I will go on showing the electrical characterization of different low dimensional systems: long molecular wires, water molecules under extreme confinement, few layer antimonene and ultrathin hexagonal Boron Nitride (hBN) layers.
