2D materials display very promising intrinsic material properties, with multiple applications in electronics, photonics, and sensing. In particular layered platinum diselenide has shown high potential due to its layer-dependent tunable bandgap, low-temperature growth, and high environmental stability. Here, the conformal and area selective (AS) low-temperature growth of layered PtSe 2 is presented defining a new paradigm for 2D material integration. The thermally-assisted conversion of platinum which is deposited by AS atomic layer deposition to PtSe 2 is demonstrated on various substrates with a distinct 3D topography. Further the viability of the approach is presented by successful on-chip integration of hybrid semiconductor devices, namely by the manufacture of a highly sensitive ammonia sensors channel with 3D topography and fully integrated infrared-photodetectors on silicon photonics waveguides. The presented methodologies of conformal and AS growth therefore lay the foundation for new design routes for the synthesis of more complex hybrid structures with 2D materials.

“…The excellent properties of transition metal chalcogenides as field-effect transistor (FET) sensors and chemiresistive gas sensors have also been explored for poisonous gases such as NO2 and NH3 that could cause significant harm to the environment (Figure 7a) (Kim et al, 2019). Moudgil et al (2020) designed a highly efficient nanostructured PtSe2 FET to detect toxic gas. It was observed that the device exhibited excellent Nitrogen dioxide (NO2) sensing properties of 2220 % and 675 % for 10 ppm and 1 ppm concentrations of NO2, respectively, at room temperature.…”

The frequent release of toxic compounds into the environment has caused substantial pollution of different aspects of the ecosystem. Thus, the need for suitable materials for environmental remediation is in high demand. Although many 2D materials with remarkable properties have been synthesized for the remediation of toxic pollutants of organic and inorganic origin, transition metal dichalcogenides (TMDs) have gathered extensive recognition lately, owing to their intriguing photocatalytic properties and tunable functionality that offers promising prospects for the decontamination, degradation, adsorption, and removal of these toxic pollutants. Therefore, this review provides the recent advancement of photocatalytic TMDs and the mechanism of their performance towards environmental remediation. Also, insights on new perspectives were highlighted.

Organic and inorganic hybrid field-effect transistors (FETs), utilizing layered molybdenum diselenide (MoSe 2 ) and an organic semiconductor poly(3-hexylthiophene) (P3HT), are presented for biosensing applications. A new hybrid device structure that combines organic (P3HT) and inorganic (MoSe 2 ) components is showcased for accurate and selective bioanalyte detection in human bodily fluids to overcome 2D-transition metal dichalcogenides (TMDs) nonspecific interactions. This hybrid structure utilizes organic and inorganic semiconductors' high surface-to-volume ratio, carrier transport, and conductivity for biosensing. Ammonia concentrations in saliva and plasma are closely linked to physiological and pathological conditions of the human body. A highly sensitive hybrid FET biosensor detects total ammonia (NH 4 + and NH 3 ) from 0.5 μM to 1 mM concentrations, with a detection limit of 0.65 μM in human bodily fluids. The sensor's ammonia specificity in artificial saliva against interfering species is showcased. Furthermore, the fabricated hybrid FET device exhibits a stable and repeatable response to ammonia in both saliva and plasma, achieving a remarkable response level of 2300 at a 1 mM concentration of ammonia, surpassing existing literature by 10-fold. This hybrid FET biosensing platform holds significant promise for developing a precise tool for the real-time monitoring of ammonia concentrations in human biological fluids, offering potential applications in point-of-care diagnostics.
