Spatiotemporal Confinement of Redox Reactivity at the Silicon–Electrolyte Interface by a Light Stimulus

Abstract

Specific scenarios require the confinement of chemical reactivity at a precise location and time. For instance, localizing chemical reactivity is required to maintain life. The ability to mimic such natural processes have answered everlasting questions of biology, and many current technologies rely on spatiotemporally controlling chemical reactivity. However, triggering transient chemical changes at a specific site remains a challenging task. This thesis shows that chemical reactions can be addressed with spatiotemporal control by means of modulating the reaction kinetics at a semiconductor surface by using a focused light stimulus.
