“…90,94) The bandwidth can reach GHz range. Besides, BN based PDs begin to attract substantial attentions for solar-blind detection [102][103][104] due to a wide bandgap of 5.2 eV (hexagonal BN) or 6.4 eV (cubic BN). 116) In addition, groups of novel materials including ZnO, 105,106) Ga 2 O 3 , 107-109) MgZnO, [110][111][112] and two-dimensional (2D) perovskite 113) and nanostructures in the form of superlattice (SL), 103) nanowires (NWs), core-shell structures 109) have emerged thanks to the advances in material growth and fabrication techniques.…”

Underwater wireless optical communication (UWOC) is a wireless communication technology that uses visible light to transmit data in underwater environment. Compared to radio-frequency (RF) and acoustic underwater techniques, UWOC has many advantages including large information bandwidth, unlicensed spectrum and low power requirements. This review paper provides an overview of the latest UWOC research. Additionally, we present a detailed description of transmitter and receiver technologies which are key components of UWOC systems. Moreover, studies investigating underwater optical channel models for both simple attenuation and the impact of turbulence including air bubbles and inhomogeneous salinity and temperature are also described. Future research challenges are identified and outlined.

“…cBN is also very interesting because it is the semiconductor with the lowest cutoff (180 nm), making it a great material for the study of the UV Sun. Figure 3 shows the relative photoresponse of different photodetectors (Soltani 2008;Benmoussa 2008aBenmoussa , 2008b) From left to right: MSM cBN at +30 V(dark yellow), MSM AlN at +30 V(pink), diamond MSM at +5 V(light blue), MSM Al 0.8 Ga 0.2 N at +20 V, Al 0.5 Ga 0.5 N at +20 V and Schottky GaN diode at -1V. The very sharp cutoff match with the expected one from the bulk materials (see IOFFE we site) i.e.…”

Abstract. The next ESA spatial mission planned to study the Sun, Solar Orbiter (SO), necessitates very innovative EUV detectors. The commonly used silicon detectors suffer important limitations mainly in terms of UV robustness and dark current level. An alternative comes from diamond or III-nitride materials. In these materials, the radiation hardness, solar blindness and dark current are improved due to their wide bandgap. This paper presents the new developments on wide bandgap materials at the Royal Observatory of Belgium (ROB). We present also the LYRA instrument, the BOLD project, and the EUI instrument suite.

Future missions for space astronomy and solar research require innovative vacuum ultraviolet (VUV) photodetectors. Present UV and VUV detectors exhibit serious limitations in performance, technology complexity and lifetime stability. New developments of metal-semiconductor-metal (MSM) solar-blind photodetectors based on diamond, cubic boron nitride (c-BN), and wurtzite aluminium nitride (AlN) are reported. In the wavelength range of interest, the characteristics of the MSM photodetectors present extremely low dark current, high breakdown voltage, and good responsivity. Diamond, c-BN, and AlN MSM photodetectors are sensitive and stable under UV irradiation. They show a 200 nm to 400 nm rejection ratio of more than four orders of magnitude and demonstrate the advantages of wide band gap materials for VUV radiation detection in space.
