IMRE Seminar on "Atomic, Molecular and Quantum Structures on Silicon Surfaces"
30 Sep 14 (Tue) - 10.00am - 11.00am
Scanning tunnelling microscopes (STM) can be used to investigate, create, and manipulate atomic- and molecular-scale structures on semiconductor surfaces. Dr. Schofield will be investigating the modification of semiconductor surfaces through the creation of quantum atomic-scale point defects, and the attachment and manipulation of organic molecules. In this talk, Dr. Schofield will describe the recent work demonstrating the formation of 1- and 2-dimensional atomic-scale quantum dots formed of individual dangling bonds where they are able to directly map extended excited state wave functions, and the recent work of imaged probability distribution of ground state s-like wave functions of substitutional as donor atoms in silicon.
