Carlos Rodriguez: Investigation and application of the Physical doping mechanisms on single layer graphene, last week.
This week, the last week, my mentor had to make a trip, so I been practicing my presentation with my lab parter. Then I went to the beach for the last time with some friends. I went to the closing ceremony to present, and I received my recognition of the program. I am so happy […]
Carlos Rodriguez: Investigation and application of the Physical doping mechanisms on single layer graphene, week six.
This week, we been transferring and preparing more samples of graphene and annealing them to test them and follow with our comparisons of their results. Another thing we did is install a humidity sensor in the conductivity set up that we did. The process of install this sensor was a little hard for me and […]
Carlos Rodriguez: Investigation and application of the Physical doping mechanisms on single layer graphene, week five.
We started preparing a solution of 10% phosphoric acid and 90% Deionized water. After that we used this solution to eliminate the aluminum dioxide from the back side of the sample to apply electric current there. The reason why we put the aluminum dioxide is because we are trying to keep the doping type of […]
Carlos Rodriguez: Investigation and application of the Physical doping mechanisms on single layer graphene, week four.
this week we continue with the process of preparing graphene samples to test them. This time we apply silicon dioxide around the samples. We use this dioxide to isolate our graphene sample from the environment. We did this because when we exposed it to the environment, graphene changed its resistivity little by little when it […]
Carlos Rodriguez: Investigation and application of the Physical doping mechanisms on single layer graphene, week three.
This is my 3rd week in my project at UCSD. In this week, we been preparing samples of graphene. The process to get ready a sample of graphene to be tested is a little long because it needs to be submerged in acetone a couple hours and then be in the oven for another two or […]
Carlos Rodriguez: Investigation and application of the Physical doping mechanisms on single layer graphene, week two.
This week we were learning how to use codes and know their functions. My mentor was explaining how to use them properly. These codes can be used to form a wide variety of functions, like you can use them to control laboratory tools and much more. During the week, we had to replace a device called […]
Carlos Rodriguez: Investigation and application of the Physical doping mechanisms on single layer graphene at UCSD, week one.
My name is Carlos Rodriguez. I’m from Montrose High School. My internship is at UCSD in La Jolla, San Diego California. I’m in a research program called ENLACE. I arrived San Diego on Sunday June 24th. I checked in and got my keys for of my dorm. I introduced myself to my roomies and met […]
