Although the effect of resonant tunneling in metal-double-insulator-metal (MIM) diodes has been predicted for over two decades, no experimental demonstrations have been reported at the low voltages needed for energy harvesting rectenna applications. Using quantum-well engineering, we demonstrate the effects of resonant tunneling in a Ni/NiO/AlO/Cr/Au MIM structures and achieve the usually mutually exclusive desired characteristics of low resistance ([Formula: see text] 13 kΩ for 0.035 μm) and high responsivity (β = 0.

- - Ellipsometry was employed to analyze how light interacts with a thin film of CH3NH3PbI3 (MAPI), an organic-inorganic hybrid perovskite, on a silicon wafer.
- - The study measured the amplitude ratio and phase shift of the light, which helps understand the optical properties of the material.
- - A multi-oscillator model was used to determine the refractive index and extinction coefficient across a wavelength range of 300 to 1500 nm from the collected data.
