Additive GaN solid immersion lenses for enhanced photon extraction efficiency from diamond color centers
Xingrui Cheng, Nils Kolja Wessling, Saptarsi Ghosh +9
Effective light extraction from optically active solid-state spin centres inside high-index semiconductor host crystals is an important factor in integrating these pseudo-atomic ce…
Fabrication and transfer print based integration of free-standing GaN membrane micro-lenses onto semiconductor chips
Nils Kolja Wessling, Saptarsi Ghosh, Benoit Guilhabert +5
We demonstrate the back-end integration of broadband, high-NA GaN micro-lenses by micro-assembly onto non-native semiconductor substrates. We developed a highly parallel micro-fabr…
Magnetic properties of nickel electrodeposited on porous GaN substrates with infiltrated and laminated connectivity
Yana Grishchenko, Josh Dawson, Saptarsi Ghosh +6
We studied the magnetic properties of ferromagnetic-semiconductor composites based on nickel and porous-GaN, motivated by the effort to couple magnetic and semiconductor functional…
