“…These detectors have many applications, including thermal imaging, energy harvesting, and target tracking [2]- [4]. Our study is directed at fabricating a thermal LWIR image sensor that operates without biasing, at room temperature, and has a small "footprint," to fit in a 10 μm × 10 μm pixel area.…”

“…They are constructed from an antenna element that receives the incident infrared radiation and a detector element that rectifies the radiation-induced antenna currents. Previously, devices were fabricated with metal-oxide-metal diodes as detector elements [4], [5]. The rectification of tunneling currents was assumed to be the dominant detection mechanism of the diodes.…”

Unbiased, uncooled, and frequency-selective antenna-coupled nanowire thermocouples have been fabricated out of different metal combinations and characterized for infrared detection. The relative Seebeck coefficient of the nanowire thermocouples was measured with a characterization platform, which is colocated on the same chip as the detectors. The area of the hot junction of the nanowire thermocouple is approximately 75 nm × 75 nm. The antenna-coupled thermocouples show polarization dependence with a maximum normalized detectivity (D * ) of 1.94 × 10 5 cm · √ Hz/W.

“…Fabrication of antenna-coupled MOM diodes is accomplished with a single-electron-beam lithography exposure and electron beam evaporation of two metals with an intermediate oxidation step [1], [18]. By performing the evaporation at two opposing angles, a small overlap area, typically 75 75 nm , is generated where the two metals coincide beneath a suspended bridge of undercut electron beam resist [ Fig.…”

“…I NFRARED (IR) dipole antenna-coupled metal-oxidemetal (MOM) tunnel diodes provide a unique detection mechanism that allows for determination of the polarization and wavelength of an optical field [1]. By integrating the MOM diode with a phased-array antenna, the angle of incidence and degree of coherence of received IR radiation can also be determined [2], [3].…”

Measured and simulated angular response patterns at 10.6 m demonstrate considerable improvement in angular resolution with a four-element phased-array antenna versus that of a two-element array. Due to propagation loss in the transmission line that connects the antenna elements, further resolution improvement is minimal with a six-element phased array. Additional measurements of a two-element array with increased metal thickness indicate that further improvement in angular resolution is possible by reducing propagation loss in the transmission line. With the combination of additional antenna elements and reduced propagation loss, substantial improvement in the angular resolution of off-broadside performance is also observed. All devices use a metal-oxide-metal tunnel diode as the detector element.Index Terms-Dipole antennas, directional antennas, infrared detectors, phased arrays.

“…Metal-oxide-metal (MOM) diodes have potential applications in the rectification of THz radiation because of their high switching speed of operation [1][2][3][4]. The use of dissimilar metals produces an asymmetric, non-linear I-V characteristic, resulting in a net current when rectifying.…”
