Controlled Spalling of Single Crystal 4H-SiC Bulk Substrates
Connor P Horn, Christina Wicker, Antoni Wellisz +5
We detail several scientific and engineering innovations which enable the controlled spalling of 10 - 50 micron thick films of single crystal 4H silicon carbide (4H-SiC) from bulk…

Coherent Erbium Spin Defects in Colloidal Nanocrystal Hosts
Joeson Wong, Mykyta Onizhuk, Jonah Nagura +13
We demonstrate nearly a microsecond of spin coherence in Er3+ ions doped in cerium dioxide nanocrystal hosts, despite a large gyromagnetic ratio and nanometric proximity of the spi…

Extended spin relaxation times of optically addressed telecom defects in silicon carbide
Jonghoon Ahn, Christina Wicker, Nolan Bitner +7
Optically interfaced solid-state defects are promising candidates for quantum communication technologies. The ideal defect system would feature bright telecom emission, long-lived…
