Optically variable devices (OVDs) are in tremendous demand as optical indicators against
the increasing threat of counterfeiting. Conventional OVDs are exposed to the danger of …

Optical antennas are devices that convert freely propagating optical radiation into localized
energy, and vice versa. They enable the control and manipulation of optical fields at the …

Abstract Metal–insulator–metal (MIM) diodes are among the most promising candidates for
applications in the high frequency regime. Owing to the tunneling dominant current …

The current-voltage (IV) characteristics of metal/insulator/metal (MIM) diodes illuminated at
optical frequencies are modeled using a semiclassical approach that accounts for the …

Signal-to-noise ratio (SNR) is a valuable figure of merit in determining the operating scope
of infrared detectors. Antenna-couple metal-oxide-metal diodes have been shown to detect …

131 Effectively controlling quantum mechanical tunneling through an ultrathin dielectric
represents a fundamental materials challenge in the quest for high-performance …

Harevesting energy from waste heat which fluctuates between, approximately, 250 K and
1500 K, ie, peaking at 2–11 μm, could be a game changer in terms of tapping on to …

A quantum‐tunneling metal‐insulator‐metal (MIM) diode is fabricated by atmospheric
pressure chemical vapor deposition (AP‐CVD) for the first time. This scalable method is …

Although the effect of resonant tunneling in metal-double-insulator-metal (MI2M) diodes has
been predicted for over two decades, no experimental demonstrations have been reported …

Optical antennas have been proposed as an alternative option for solar energy harvesting.
In this work the power conversion efficiency of broadband antennas, log-periodic, square …
