In addition to photoresponsivity, the normalized photocurrent-to-dark current ratio (NPDR), defined as responsivity divided by the dark current, is another important parameter that characterizes ...

In this work, the variance and the magnitude of a noise-dependent spectral bias are calculated as a function of the system responsivity (r) and the noise level in its estimate (sigma(r)). The ...

Researchers from the University of Illinois at Urbana-Champaign have demonstrated a new approach to modifying the light absorption and stretchability of atomically thin two-dimensional (2D ...

However, the weak optical absorption of graphene limits its photo-responsivity. To address this, graphene has been integrated into nanocavities, microcavities, and plasmon resonators; yet, these ...

Patients with severe traumatic brain injuries had increased neural responsivity to vocal stimuli in language regions when provided with familiar auditory sensory training, according to a recently ...

a, AFM image of 2D vermiculite. b, PFM amplitude map of 2D vermiculite. c, PFM phase map of 2D vermiculite. d. Comparison of electric field responsivity of 2D vermiculite LC and other media.

The team’s tests showed that their proof-of-concept photodiode outperformed not only existing germanium photodiodes but also commercial indium gallium arsenide photodiodes in responsivity. The new ...
