Artificial spin ice (ASI) systems are arrays of orderly arranged magnetic nanoislands fabricated by nanolithographic methods. They form a perfect medium to study spin wave propagation and interactions between the nanomagnets. The potential application is in magnon computing which utilizes the precession of the electron spin for information transport and processing. This field has huge potential to replace CMOS technologies as it does not dissipate significant power.
ASI systems are typically fabricated by lithographic techniques which impose stringent alignment requirement on the fabrication. Our team has developed a self-aligned method via multiple stationary deposition stages to transfer patterns and as a result, unique and novel nanostructures can be designed and fabricated with material deposited at desired locations. Current work via magnetic force microscopy and simulations have shown interesting results.
NUS currently has the opening of a Research Engineer. The job provides an opportunity to work with state-of-the-art facilities in NUS Engineering E6 NanoFab cleanrooms. The candidate will acquire experience in nanofabrication techniques such as evaporation, self-assembly, and lithography. He/she will also be exposed to characterization techniques such as scanning electron microscopy, magnetic force microscopy, Brillouin Light Scattering spectroscopy, ferromagnetic resonance etc. Opportunity is available for the candidate to enroll in a part-time higher degree concurrently.
The objectives of the research position are as follows:
- Design and fabricate various novel structures via the stepwise nanosphere lithography technique with different materials
- Characterize the nanostructures by magnetic force microscopy, scanning electron microscopy, Brillouin Light Scattering, ferromagnetic resonance and other techniques
- Simulate nanomagnetic structures to explain/correlate with experimental phenomena
Interested applicants may also send their motivation letter and curriculum vitae via email to A/P Vivian Ng (email@example.com ).
- At least a recognized degree in BEng or BSc equivalent with interest in the microelectronics area
- Strong problem solving skills
- Aspiration to pursue a graduate degree is preferred
- Excellent written and spoken communication
- Enthusiasm to work in a team comprising honors year students and postdoctoral fellows
- Work experience in a relevant area is an advantage but not necessary
- Open to fixed-term contract
- Salary would commensurate with work experience
