However, experimental studies on GaGeTe in the infrared region are lacking and this exciting property has not been explored yet. This can be attributed to their small optical bandgap and high carrier mobility. Recent theoretical studies proposed that two-dimensional (2D) GaGeTe crystals have promising high detection sensitivity at infrared wavelengths and can offer ultra-fast operation. The ensuing diode technology can be used in flexible complementary circuits targeting low-energy-budget applications for the emerging internet of things device ecosystem.

The enhanced diode and circuit performance is attributed to the improved charge transport across CuSCN induced by C60F48. Herein, we report on CuSCN Schottky diodes, where the semiconductor is processed from solution, featuring coplanar Al-Au nanogap electrodes (100 mV for a VIN = ±5 V at the commercially relevant frequency of 13.56 MHz. Although a number of high-frequency n-type diodes and rectifiers have been demonstrated, the progress with p-type diodes is lagging behind, mainly due to the intrinsically low conductivities of existing p-type semiconducting materials that are compatible with low-temperature, flexible, substrate-friendly processes. Schottky diodes based on inexpensive materials that can be processed using simple manufacturing methods are of particular importance for the next generation of flexible electronics. The results obtained give insight into the growth of crystalline WSe2 via sacrificial film selenization. For the electrical characterization, field effect transistors (FETs) were made to measure output and transfer curves. On-chip photoconductive devices were made using the standard photolithography process, and their photoresponse was investigated with 405 nm wavelength light. The structure and chemical composition were confirmed by X-ray diffraction and micro-Raman spectroscopy, respectively. Surface morphology of the as-grown films was studied using a scanning electron microscope complemented with an atomic force microscope.

Here, we have studied and compared properties of thin crystalline WSe2 films prepared via selenization of sputter-deposited sacrificial WO3 and W films. However, its use is still limited, mainly due to a lack of understanding the growth mechanisms involved. A potential large-scale 2D WSe2 synthesis method is conversion (selenization) of a pre-deposited sacrificial precursor coating. One of the remaining main challenges is the large area growth of high-quality films. Layered two-dimensional (2D) materials, such as p-type WSe2, are potential key materials in the manufacture of the next generation electronic devices. Supplementary Fig. 10 would explain more. Note that the demodulated signals quite resemble those of real audio as an envelope of AM signals.
