SURF: Announcements of Opportunity
Below are Announcements of Opportunity posted by Caltech faculty and JPL technical staff for the SURF program. Additional AOs for the Amgen Scholars program can be found here.
Specific GROWTH projects being offerred for summer 2017 can be found here.
Students pursuing opportunities at JPL must be U.S. citizens or U.S. permanent residents.
Each AO indicates whether or not it is open to non-Caltech students. If an AO is NOT open to non-Caltech students, please DO NOT contact the mentor.
Announcements of Opportunity are posted as they are received. Please check back regularly for new AO submissions! Remember: This is just one way that you can go about identifying a suitable project and/or mentor.
Announcements for external summer programs are listed here.

We are entering a new era of materials research, one in which materials with properties superior to those of any known are being designed with the aid of the computer. Our theory collaborators are continually coming up with new arrangements of atoms, customized at the atomic-layer level, that they believe will exhibit even better properties. A major challenge, however, is to prepare these materials to realize these properties. This is our research goal and we do it using a thin film growth technique called molecular-beam epitaxy (MBE). My group, which has expertise in synthesis, works as a team together with other groups with expertise in theory and characterization to target and unleash the record-breaking properties of oxide materials. Using this “materials-by-design” approach, our team has achieved some major successes including a new multiferroic material in which ferrimagnetism can be controlled by an electric field at room temperature (J.A. Mundy et al. “Atomically Engineered Ferroic Layers Yield a Room-Temperature Magnetoelectric Multiferroic,” Nature 537 (2016) 523–527.). Having understood the inner workings of this new multiferroic, we are eager to create an even better manifestation of it with superior performance.
|Description:||As a SURF student, you will be an integral member of our research team working to make a multiferroic material that enables the electrical control of magnetism at room temperature. At first you will gain familiarity with the characterization techniques you will be using to assess the structural, magnetic, and ferroelectric properties of the new materials that are being created by your co-mentor using MBE. Once you have learned the operational details of x-ray diffraction, vibrating sample magnetometry, and polarization vs. electric field measurements, you will measure the films being grown by your co-mentor to provide important feedback allowing optimized conditions to be found for the growth of a new oxide material believed to be a superior multiferroic. You will brainstorm together with the entire team—involving theory, synthesis, and characterization—to gain understanding of the connection between the structure and properties of the materials made and devise a route to create a superior multiferroic.|
