Abstract
Scanning tunneling microscopy (STM) is a pivotal surface-imaging technique that reveals intricate atomic and electronic structures. Its remarkable subatomic spatial resolution, coupled with the energy-resolved local density of states, provides insights into both the local electronic properties and global band structures. Recent advancements in STM, including a breakthrough in charge-density manipulation, have broadened the scope of its research. This review delves into the experimental methodologies for probing the electronic structures of various topological materials, including topological insulators, semimetals, and superconductors. It explores techniques such as Landau-level spectroscopy and quasi-particle interference measurements. Additionally, it examines the influence of topological phase transitions and electron correlations that can be modulated by in situ electrical fields in two-dimensional samples.
期刊介绍：
Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications.
Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques.
Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals.
Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review.
The Journal is owned by the Korean Physical Society.
