Book Description
The aim of the work presented therein is to take advantage of scanning tunneling microscope’s (STM) capability for operation under a variety of environments under real time and at atomic resolution to monitor adsorbate structures and mobility under high pressures, as well as to design a new generation of STM systems that allow imaging in situ at both higher pressures (35 atm) and temperatures (350 °C).

Book Description
Our research focuses on taking advantage of the ability of scanning tunneling microscopy (STM) to operate at high-temperatures and high-pressures while still providing real-time atomic resolution images. We also utilize high-pressure x-ray photoelectron spectroscopy (HPXPS) to monitor systems under identical conditions thus giving us chemical information to compare and contrast with the structural and dynamic data provided by STM.

Pages : 38
Book Description
Some prospects for applying scanning tunneling microscopy (STM) as an in-situ atomic-resolution probe of adlayer structure at ordered metal-solution interfaces are considered with respect to both equilibrium and reactive adsorbate systems. Illustrative results of the former type are presented for the potential-dependent adsorption of iodide at low-index gold electrodes. The virtues of acquiring composite-domain STM Images, where the electrode potential is altered during data acquisition so to form or remove the adsorbed adlayer, are noted. By generating temporally and spatially adjacent domains featuring substrate and adlayer images in this fashion, the registry between the former and latter atomic arrangements can be deduced with high precision. The suitability of in-situ STM for examining real-space dynamics of surface physical and chemical processes is illustrated for potential-induced reconstruction of Au(100) and for the electrooxidative polymerization of iodide and sulfide. Some limitations as well as strengths of in-situ STM for these purposes are briefly outlined with regard to its anticipated role in the development of in-situ electrochemical surface science.
