Experimental observation of ballistic to diffusive transition in AlN thin films
Md Shafkat Bin Hoque, Michael E. Liao, Saman Zare +10
Bulk AlN possesses high thermal conductivity due to long phonon mean-free-paths, high group velocity, and long lifetimes. However, the thermal transport scenario becomes very diffe…
18 GHz Solidly Mounted Resonator in Scandium Aluminum Nitride on SiO2/Ta2O5 Bragg Reflector
Omar Barrera, Nishanth Ravi, Kapil Saha +12
This work reports an acoustic solidly mounted resonator (SMR) at 18.64 GHz, among the highest operating frequencies reported. The device is built in scandium aluminum nitride (ScAl…
Imaging Hot Photocarrier Transfer across a Semiconductor Heterojunction with Ultrafast Electron Microscopy
Basamat S. Shaheen, Kenny Huynh, Yujie Quan +5
Semiconductor heterojunctions have gained significant attention for efficient optoelectronic devices owing to their unique interfaces and synergistic effects. Interaction between c…
Approaching the Practical Conductivity Limits of Aerosol Jet Printed Silver
Eva S. Rosker, Michael T. Barako, Evan Nguyen +6
Previous efforts to directly write conductive metals have been narrowly focused on nanoparticle ink suspensions that require aggressive sintering (>200 °C) and result in low-densit…
Simultaneous Evaluation of Heat Capacity and In-plane Thermal Conductivity of Nanocrystalline Diamond Thin Films
Luke Yates, Zhe Cheng, Tingyu Bai +6
As wide bandgap electronic devices have continued to advance in both size reduction and power handling capabilities, heat dissipation has become a significant concern. To mitigate…
Molecular Beam Epitaxy Growth of High Crystalline Quality LiNbO
M. Brooks Tellekamp, Joshua C. Shank, Mark S. Goorsky +1
Lithium niobate is a multi-functional material with wide reaching applications in acoustics, optics, and electronics. Commercial applications for lithium niobate require high cryst…
