Sputtering
The objective is to combine different materials possessing certain traits and obtaining a new material that interacts with light in a desired way. This is possible by extracting atoms from a material, known as a target, and deposited onto a substrate forming a layer on the substrate's surface. This can be repeated many times until the optimal number of layers is obtained. All the layers form what is known as a thin film, which is actually a material possessing the expected response.
Laser Ablation
Laser ablation is the process of removing material from a sample by focusing an intense pulsed laser beam on it. The employed laser systems usually emit from the near infrared to the near ultraviolet region of the electromagnetic spectrum; they need to have pulse durations of a few nanoseconds to deliver power of a few GWatts per squared centimiter.
Spectroscopy
If the light emitted by an object passes through a prism it is separated into a set of colors. All this colors are indeed a measurement of radiation intensity as a function of wavelength and forms what is known as electromagnetic spectrum. If we regard chemical elements in the periodic table we will find a unique set of colors for each element.
Ellipsometry
Ellipsometry is a technique utilized to analyze the optical properties of thin films such as its composition, dielectric permittivity, and the material's layer's thickness.
AFM
Atomic Force Microscopy (AFM) is a technique used to obtain the physical properties of surfaces at a nanometric level, such as: roughness , elastic properties, friction, and piezo- ferro-electricity. Actually, this technique allows to obtain a 3D topography of a sample's surface. More in practice, AFM consists of a mechanical arm which has a very small pyramid shaped tip called a cantilever which is dragged across the sample's surface.
