Waveguide based compact silicon Schottky photodetector with enhanced responsivity in the telecom spectral band
TL;DR: The combination of enhanced quantum efficiency together with a simple fabrication process provides a promising platform for the realization of all silicon photodetectors and their integration with other nanophotonic and nanoplasmonic structures towards the construction of monolithic silicon opto-electronic circuitry on-chip.
Journal ArticleDOI
AlGaN ultraviolet photoconductors grown on sapphire
TL;DR: In this article, the spectral responsivity of the GaN detector at 360 nm is about 1 A/W biased at 8 V at room temperature, and the carrier lifetime derived from the voltage-dependent responsivity is 0.13−0.36 ms.

The role of amorphous silicon and tunneling in heterojunction with intrinsic thin layer (HIT) solar cells
Ana Kanevce,Wyatt K. Metzger +1 more
TL;DR: In this article, the authors analyzed heterojunction with intrinsic thin layer (HIT) solar cells using numerical simulations and found that the differences between the device physics of cells with p- and n-type crystalline silicon (c-Si) wafers are substantial.
Journal ArticleDOI
Optimum mobility, contact properties, and open-circuit voltage of organic solar cells: A drift-diffusion simulation study
TL;DR: In this article, the existence of an optimum mobility derived from simulation depends strongly on the assumptions made for contact and recombination properties and obtain a comprehensive picture how charge carrier mobility influences the parameters of organic solar cells.

Low-power FPGA using pre-defined dual-Vdd/dual-Vt fabrics
Fei Li,Yan Lin,Lei He,Jason Cong +3 more
TL;DR: This is the first in-depth study on applying both dual-Vdd/dual-Vt to FPGA considering circuits, fabrics and CAD algorithms and develops CAD algorithms including power-sensitivity based voltage assignment and simulated-annealing based placement to leverage such fabrics.
