High-Bandwidth Extended-SWIR GeSn Photodetectors on Silicon Achieving Ultrafast Broadband Spectroscopic Response
M. R. M. Atalla, S. Assali, S. Koelling +2
The availability of high-frequency pulsed emitters in the m wavelength range paved the way for a wealth of new applications in ultrafast spectroscopy, free-space and fibe…
Extended-SWIR Photodetection in All-Group IV Core/Shell Nanowires
Lu Luo, Simone Assali, Mahmoud R. M. Atalla +6
Group IV Ge1-xSnx semiconductors hold the premise of enabling broadband silicon-integrated infrared optoelectronics due to their tunable bandgap energy and directness. Herein, we e…
Micrometer-thick, atomically random Si0.06Ge0.90Sn0.04 for silicon-integrated infrared optoelectronics
Simone Assali, Anis Attiaoui, Sebastian Koelling +6
A true monolithic infrared photonics platform is within reach if strain and bandgap energy can be independently engineered in SiGeSn semiconductors. Herein, we investigate the stru…
Combined Iodine- and Sulfur-based Treatments for an Effective Passivation of GeSn Surface
Léonor Groell, Anis Attiaoui, Simone Assali +1
GeSn alloys are metastable semiconductors that have been proposed as building blocks for silicon-integrated short-wave and mid-wave infrared photonic and sensing platforms. Exploit…
