Transparent Conductive Oxides (TCOs)

Jul 9, 2026 | Glossary of Spectroscopy Terms, Thin Film

Transparent Conductive Oxides (TCOs) Transparent conductive oxides (TCOs) are electrically conductive materials that maintain high optical transparency. Common TCOs include indium tin oxide (ITO) and aluminum-doped zinc oxide (AZO), which are widely used in displays,...

Interference Fringes

Jul 9, 2026 | Glossary of Spectroscopy Terms, Thin Film

Interference Fringes Interference fringes are the repeating peaks and valleys observed in reflected or transmitted spectra when light interacts with a thin film. The spacing and intensity of these fringes depend on film thickness, optical constants, wavelength, and...

Optical Interference

Jul 9, 2026 | Glossary of Spectroscopy Terms, Thin Film

Optical Interference Optical interference occurs when light reflected from multiple thin film interfaces combines to produce constructive and destructive interference patterns. These interference fringes contain valuable information about film thickness, refractive...

Multilayer Thin Films

Jul 9, 2026 | Glossary of Spectroscopy Terms, Thin Film

Multilayer Thin Films Many advanced optical and electronic devices contain multiple thin film layers, each engineered to perform a specific optical or electrical function. These multilayer stacks may include oxides, nitrides, transparent conductive oxides, dielectric...

Thin Film Modeling

Jul 9, 2026 | Glossary of Spectroscopy Terms, Thin Film

Thin Film Modeling Thin film modeling is the process of mathematically simulating how light interacts with one or more thin film layers. By comparing measured spectra with theoretical optical models, engineers can determine film thickness, refractive index, extinction...
