Summary
Heinrich Rohrer's collected papers in the *IBM Journal of Research and Development* address fundamental aspects of surface physics and superconductivity. His work, particularly that which led to his Nobel Prize, centers on the development and application of the scanning tunneling microscope (STM). The central thesis is that atomically resolved imaging of surfaces is achievable and crucial for understanding their electronic and structural properties.
Readers gain insight into the experimental techniques and theoretical underpinnings that enabled the visualization of individual atoms on surfaces. Key ideas include the quantum mechanical tunneling effect as the basis for STM, the manipulation of atoms using the STM tip, and the application of these techniques to study surface reconstruction, adsorption, and the electronic states of materials, including those exhibiting superconductivity.

Key concepts
- Scanning Tunneling Microscope (STM) — A microscope that uses the quantum mechanical phenomenon of electron tunneling to image surfaces at the atomic level.
- Quantum Tunneling — The quantum mechanical effect where a particle can pass through a potential energy barrier that it classically would not have enough energy to overcome.
- Surface Reconstruction — The process where the atoms on the surface of a crystal rearrange themselves into a different structure than the bulk material.
- Adsorption — The adhesion of atoms or molecules from a gas, liquid, or dissolved solid to a surface.
- Superconductivity — A phenomenon observed in certain materials where electrical resistance drops to zero below a critical temperature.
