In this review, we have comprehensively elaborated on the various materials suitable for the
infrared (IR) bolometer applications and also provided the underlying mechanisms of …

In recent years, the field of nanophotonics has progressively developed. However, constant
demand for the development of new light source still exists at the nanometric scale. Light …

Incorporating nano-and microelectromechanical systems (NEMS/MEMS)-based sensors in
clothing and developing more compact and flexible devices have gained popularity recently …

Discovery of infrared radiation (IR) was an important step in understanding the hidden
secrets of nature, which could be unraveled only after “seeing” this invisible spectrum. This …

Vanadium oxide (VO_x) microbolometers enable the construction of high-performance yet
low-cost and uncooled imaging detectors in the mid-infrared spectrum. Typical micro …

We have investigated an uncooled infrared (IR) detector utilizing a dual level architecture.
This was achieved by combining two-microbolometer stack in the vertical direction to …

Thermal photodetectors rely on thermally sensitive materials to convert the heat generated
from incoming light to an electrical signal and are used in, for example, focal plane arrays …

This article investigated metasurface-enabled uncooled silicon germanium oxide (Si 0.425
Ge 0.512 O 0.063) infrared (IR) microbolometers. The metasurface was used to engineer the …

Here we report a metal-insulator-metal (MIM) based infrared plasmonic metamaterial
absorber consisting of deep subwavelength meander line nanoantennas. High absorption …

To realize high-resolution thermal images with high quality, it is essential to improve the
noise characteristics of the widely adopted uncooled microbolometers. In this work, we …
