this week I spent using ultraviolet visible spectroscopy to analyze my films. The UV visible spectrometer uses a prism to diffract light into many wavelengths and emitting them through the sample. The wavelength is controlled by the angle that the prison is directing the refracted...
This week I’ve been using the evaporator to create silver films of 100 to 5 nanometers in increments of 10. My latest slide is 40 nm, it takes about five hours to create one slide. The pumps take a long time to pump out all...
This week while working with the evaporator to deposit silver onto microscopic films the switches in the evaporator broke. I spent most of the week designing new switches and problem shooting the evaporator. I got it working again and am continuing with my experiment. Using some...
In my lab I am taking microscopic slides and turning them into thin films of silver (1 to 100 nm thick) using a evaporator to evenly distribute the silver onto the surface of the films. Then I will be measuring them with an ellipsometer to...
I’m Benjamin Leu, and I’m spending my summer at the University of Houston, in Houston Texas where I use electrochemistry and cyclic voltammetry to calculate for the real surface area of different metals. The fist week here I got to meet many different professors and...
