High-temperature goniometer for thin film growth and ion scattering studies
Abstract
<jats:p>We have developed a laser-heated six-axis goniometer for oxide thin film growth and ion scattering studies. The goniometer requires only a single CF152 flange for mounting in a vacuum chamber and includes three positioning and three rotational degrees of freedom. All translation and rotation axes are decoupled. A sample with a maximum size of 10 mm×10 mm can be heated to 1200 °C in a pure oxygen environment. The heating source is a 300 W continuous wave Nd:YAG laser. Light from the laser is brought to the sample stage with a combination of flexible and rigid optical fibers. The goniometer includes a motorized manipulator for two ablation targets, making it possible to grow thin films by pulsed laser ablation. Film growth and surface structure can be monitored by reflection high-energy electron diffraction and coaxial impact collision ion scattering spectroscopy. Samples can also be transferred from the goniometer to a room-temperature scanning tunneling microscope inside the vacuum chamber.</jats:p>
