Available Resources:
UDC’s Nanotechnology Application Laboratory (NAL) self-sufficient for producing and studying microscopic (< 4 µm2) MTJMSD. NAL is equipped with microfabrication resources like a clean room, two mask aligners, thin film deposition systems (sputtering machines and thermal evaporator), environment controlled annealing furnaces etc. NAL is also equipped with characterization tools such as 1-17 GHz ferromagnetic resonance, Keithley 4200 Semiconductor parameter analyzer with I-V, C-V option, ARS low-temperature magneto transport system and SEM. To support theoretical Monte Carlo studies our computational materials lab is equipped with multiple DELL workstations with Xenon processors and 14 cores. The full list of existing capabilities is provided under Facility and Resources.
AM related Resources available at UDC: UDC has an EOSINT M280 metal 3D printer (Fig.3), We have on campus Phenom XL SEM, reflectance meter, and multiple mechanical testing resources. UDC also has collaboration with NIST and neighboring Howard University to utilize their complementary resources. Specifically, UDC will be seeking collaborative support to conduct fatigue and creep testing outside UDC campus.
Resources to be acquired: In AMP3 PROPOSAL we have requested funds for etching and patterning, optical profilometer. Requested equipment will increase our capacity to perform the research under proposed projects.
