“…5(b) shows the temperature dependence of the NEP at the fixed gate voltage V g = −4.4 V. Compared with the degradation of the responsivity R v at high temperatures, the physical mechanisms inside the degradation of the NEP include an extra factor of thermal noise, which is proportional to T 0.5 . To achieve higher operation temperature, surface states of GaN HEMTs can be passivated to enhance device thermal stability 27 28 .…”

In this work, a high temperature THz detector based on a GaN high electron mobility transistor (HEMT) with nano antenna structures was fabricated and demonstrated to be able to work up to 200 °C. The THz responsivity and noise equivalent power (NEP) of the device were characterized at 0.14 THz radiation over a wide temperature range from room temperature to 200 °C. A high responsivity Rv of 15.5 and 2.7 kV/W and a low NEP of 0.58 and 10 pW/Hz0.5 were obtained at room temperature and 200 °C, respectively. The advantages of the GaN HEMT over other types of field effect transistors for high temperature terahertz detection are discussed. The physical mechanisms responsible for the temperature dependence of the responsivity and NEP of the GaN HEMT are also analyzed thoroughly.

“…The excellent cycling stability is due to the unique microstructure of the HGC/S electrode. HGC possesses micro/mesoporous structure with 0.6–3 nm pores that are surrounded by graphene, serving as highly efficient polysulfides reservoirs, which can effectively immobilize the large amount of sulfur and depress the shuttle effects of polysulfides. − On the other hand, HGC with an ultralarge SSA of ≤3182 m 2 g –1 and a large pore volume of 1.91 cm 3 g –1 can effectively accommodate the volume exapnsion of the sulfur particle during the charge/discharge process. , As a result, the HGC/S cathode shows superior cyclic stability even at high current densities.…”

Herein, a hierarchically micro/mesoporous nanocomposite of graphene and carbon nanospheres (HGC) is used as an immobilizer for a lithium−sulfur (Li−S) battery with enhanced performance. HGC derived from graphene oxides and polyvinylidene fluoride polymers, combined with the advantages of graphene and porous carbon nanospheres, exhibits a hierarchically micro/ mesoporous structure with an ultralarge specific surface area of up to 3182 m 2 g −1 and a large pore volume of 1.91 cm 3 g −1 . Graphene as a conducting network can enhance electronic conductivity, while porous nanospheres like a reservoir can effectively store and immobilize sulfur particles. HGC/sulfur electrode material obtained via a melting infusion process exhibits high reversible specific capacity of 1250 mA h g −1 with a high sulfur content of 74.5 wt %, and it still has a capacity of 916 mA h g −1 after 100 cycles, which is better than that of pristine porous graphene and carbon nanospheres. Furthermore, the relative capacity decay of the HGC/sulfur electrode is only 0.005 and 0.004% per cycle at 2 C and 4 C, respectively, after 450 charge/discharge cycles, exhibiting remarkable performance in terms of long-term electrochemical stability.

“…[1][2][3], heatable layers in defrosting windows [4,5] and electromagnetic shielding and radar stealth in the aeronautical industry [6,7]. Among many TCF materials, the investigations of amorphous transparent conductive oxide films, such as conventional indium tin oxide (ITO) and amorphous indium zinc oxide (In 2 O 3 -ZnO, IZO) films [8,9], which are deposited on the polyester substrates, have received much attention, especially in the area of canopies in the aeronautical industry. However, conductive films, such as ITO and IZO, have numerous drawbacks such as bad wear, corrosion resistance and weak erosion performance [10][11][12][13], which can dramatically limit their large-scale application in the next-generation aeronautical and optoelectronic devices.…”

Transparent conductive films (TCFs) have received much research attention in the area of aeronautical canopies. However, bad wear, corrosion resistance and weak erosion performance of TCFs dramatically limit their scalable application in the next-generation aeronautical and optoelectronic devices. To address these drawbacks, three types of optically transparent coatings, including acrylic, silicone and polyurethane (PU) coatings were developed and comparatively investigated ex situ in terms of Taber abrasion, nanoindentation and sand erosion tests to improve the wear-resistance and sand erosion abilities of ITO-coated PMMA substrates. To elucidate the sand erosion failure of the coatings, the nanoindentation technique was employed for quantitative assessment of the shape recovery abilities under probe indentation. Results show that the PU topcoats can greatly enhance the sand erosion properties, which were superior to those of acrylic and silicone topcoats. This result can be attributed to the good toughness and self-healing properties of PU topcoats. Additionally, high hardness and good Taber abrasion properties of the ITO films and silicone topcoats did not have an obvious or affirmatory effect on the sand erosion abilities, based on their brittleness and irreparable properties under sand erosion.
