Direct Spatiotemporal Imaging of Charge Carrier Dynamics in Operative Semiconductor Devices
Adriano Cola, Antonio Valletta, Isabella Farella +2
Understanding charge carrier dynamics within electronic devices is crucial, as it governs both the internal evolution of signals and the externally measurable current. Yet, direct…
Plasmonic-cavity Modulator for the Mid-IR with a Semi-transparent and Nonlinear Heavily-doped Semiconductor Mirror
Tommaso Venanzi, Raffaella Polito, Andrea Rossetti +15
We present a free-space plasmonic modulator based on a single heavily-doped semiconductor layer. We investigate its ability to modulate both the linear and nonlinear response at mi…
Electric-Field Mapping of Optically Perturbed CdTe Radiation Detectors
Adriano Cola, Lorenzo Dominici, Antonio Valletta
In radiation detectors, the spatial distribution of the electric field plays a fundamental role in their operation. Access to this field distribution is of strategic importance, es…
Modulating Low-Power Threshold Optical Bistability by Electrically Reconfigurable Free-Electron Kerr Nonlinearity
Huatian Hu, Gonzalo Ãlvarez-Pérez, Antonio Valletta +3
We propose a microscopic mechanism to electrically reconfigure the Kerr nonlinearity by modulating the concentration of free electrons in heavily doped semiconductors under a stati…
