Presenter: Prof. Frank Schreiber (Universitaet Tuebingen, Germany)

Topic: How X-rays can help to understand organic devices

Time: 10:00AM, Mar. 25th (Friday)

Location: Conference Room B, BLDG 909-1F

 

Abstract

In this lecture, we discuss different forms of the application of X-rays for the characterization of functional organic materials and devices. These are typically not single crystals, but complex layered multi-component heterostructures with non-trivial interface geometries. We illustrate how to address, using X-rays,

a)  the different scenarios of organic-organic heterostructures [1-4]

b) the interface between metal contacts and organic semiconductors [5,6] (with specific role X-ray standing waves (XSW) can play for a high-precision study) and

c)  the interface between organic semiconductors and capping layers.

We finally discuss the perspectives of using X-rays for other types of nano-structures, including in-situ monitoring of growth and structural changes [7].
