OTFD-100 in-situ x-ray scattering of organic thin film deposition


Modern materials science calls for sophisticated tools that allow X-ray investigations in defined environments and under controlled temperature conditions. Organic electronic materials have potential applications in a number of low-cost, large area electronic devices, such as flat panel displays and inexpensive solar panels. Small molecules of the series Anthracene, Tetracene, Pentacene, are model molecules for organic, semiconductor, thin films, to be used as the active layers in such devices.

 

The OTFD-100 is a compact vacuum deposition chamber for in-situ x-ray scattering studies of organic thin film growth. The system is based on a small cylindrical chamber that can be mounted on a standard four-circle diffractometer. Incident and scattered x-rays enter and exit the chamber through a curved Be foil window that covers 270 degrees, and is sealed to the body of the chamber. The sample is mounted on a post with heating and cooling from liquid nitrogen temperature to >100 centigrade. Integral to the sample stage is a multi-wire feed through to facilitate in-situ electrical transport characterization of organic semiconductor thin films. This is one of the unique capabilities of the system. In addition, the sample stage is mounted on a rotary vacuum feed through, which is mechanically coupled to the “phi” stage of the diffractometer. An effusion cell, shutter, and quartz oscillator thickness monitor are also incorporated into the system, which is pumped by a small turbomolecular pump. The system thus configured is capable of access to full reciprocal space, within the limits of the Be window.
