Black silicon avalanche photodiode with dopant-free multiplication region achieves >98% EQE
O. Leiviskä, O. Setälä, A. Haarahiltunen +3
Conventional silicon avalanche photodiodes (Si APDs) rely on highly doped regions to enable impact ionization and achieve internal gain. However, inefficient charge collection in t…
Nanostructuring SiC by sequential plasma oxidation and reactive ion etching
Joonas Isometsä, Auguste Bieleviciute, Xiaolong Liu +2
Silicon carbide (SiC) is a highly promising material for the rapidly growing UV detection industry due to its visible-blindness, low dark current, and exceptional thermal and chemi…
Efficient photon capture on germanium surfaces using industrially feasible nanostructure formation
Kexun Chen, Joonas Isometsä, Toni P. Pasanen +2
Nanostructured surfaces are known to provide excellent optical properties for various photonics devices. Fabrication of such nanoscale structures to germanium (Ge) surfaces by meta…
How much physics is in a current-voltage curve? Inferring defect properties from photovoltaic device measurements
Rachel C. Kurchin, Jeremy R. Poindexter, Ville Vähänissi +3
Defect-assisted recombination processes are critical to understand, as they frequently limit photovoltaic (PV) device performance. However, the physical parameters governing these…
