The development of high-temperature photodetectors can be beneficial for numerous applications, such as aerospace engineering, military defence and harsh-environments robotics. However, current are characterized by low photoresponsivity (<10 A/W) due to the poor optical sensitivity commonly used heat-resistant materials. Here, we report realization h-BN-encapsulated graphite/WSe2 which endure temperatures up 700 °C in air (1000 vacuum) exhibit unconventional negative photoconductivity (NPC)...
High-temperature-resistant integrated circuits with excellent flexibility, a high integration level (nanoscale transistors), and low power consumption are highly desired in many fields, including aerospace. Compared conventional SiC high-temperature transistors, transistors based on two-dimensional (2D) MoS2 have advantages of superb atomic scale, ultralow consumption. However, cannot survive at temperature drastically degrades above 200 °C. Here, we report field-effect (FETs) top/bottom...
Internet of Things sensor nodes, which integrate information acquisition, processing, exchange, and execution modules, have widely been used for unattended industrial production, environmental monitoring, other fields. However, limited battery power constrains the lifespan nodes. In this paper, we propose a near-zero-power infrared relay consists microfluidic switches metamaterial absorber (MA). When target appears, MA absorbs energy emitted from uses it to turn on switch. valid is not...
Abstract Industries such as aerospace or military have promoted the development of high-temperature photodetectors. However, current photodetectors exhibit low photoresponsivity (<10 A/W) because heat resistant materials usually poor optical sensitivity. 2D transition metal dichalcogenides demonstrate outstanding optoelectronic properties, but they cannot survive at elevated temperature. It is challenging to realize photodetector with both high-temperature-resistant capability and high...
