Application oriented Woollam WVASE Trainings Course

Short course Announcement

L.O.T.-Oriel GmbH & Co. KG together with the J.A. Woollam Co., Inc. is happy to introduce a new course on Ellipsometry Data Analysis that targets intermediate to advanced users. Students should have at least some ellipsometry experience and a proficiency with WVASE32 software. The course will be divided into sessions that include thin and thick film analysis, transparent and absorbing layers, graded, Genosc Layers, anisotropy. To support the lectures, participants will work examples on individual computers (participants need to bring their own notebook).

Genosc Layer

Learn the intimate details of our most powerful layer. Session will begin with a review of the information for standard data analysis. However, it will quickly proceed to topics including advanced oscillator types: Gauss-Lorentz, Tauc- and Cody-Lorentz, GLAD, TOLO, PSEMI-Triangle…

The Genosc layer is both powerful and versatile and we examine advanced methods that unlock the full utility of this layer. We will also discuss how to control correlation and minimize the number of free parameters.

Grading

Ellipsometry measurements are often sensitive to optical gradients within a thin film. The WVASE32 software offers a variety of models to approach graded samples – starting with the Simple Graded layer and working toward the EMA-Based Graded layer and working toward the Function–based Graded layer.

Anisotropy

Anisotropic materials provide exciting new challenges during data acquisition and analysis. Building on the Advanced Data Acquisition Session, which will introduce students to Generalized Ellipsometry and Mueller-Matrix measurements, this session will cover the methods used to characterize anisotropic materials. Students will apply the BIAXAL layer within WVASE32 toward both uniaxial and biaxial materials. Examples have been selected to introduce practical methods for both substrates and thin films; eg. like PET substrates, non-symmetric crystals, organic thin films, and Liquid Crystal layers.
