Boron nitride (bn) thin films have gained significant research interest due to their unique properties and potential applications in electronic devices. the article titled "boron nitride thin films for dielectric applications: a review" by v. bharti et al. published in the journal of applied physics in 2018 provides a comprehensive review of various synthesis methods for bn thin films. BN possesses excellent thermal stability, high electrical resistivity, good chemical inertness, and low dielectric constant, which makes it an ideal candidate for electronic applications such as insulation layers, gate dielectrics, and encapsulation layers. the most commonly used synthesis techniques for bn films include physical vapor deposition (pvd) and chemical vapor deposition (cvd). The pvd method includes processes such as sputtering, electron-beam evaporation, and pulsed laser deposition. among these techniques, sputtering is the most widely used and relatively simple technique to synt

Boron Nitride (bn) is a unique material that has attracted significant attention in recent times due to its excellent thermal, mechanical, and electrical properties. bn is a compound of boron and nitrogen atoms arranged in a hexagonal structure similar to graphene. in this review, we will discuss the application of boron nitride thin films based on the three articles provided. In an article by K. Watanabe et al., titled "Growth and Characterization of Hexagonal Boron Nitride Thin Films," focuses on the synthesis and characterization of high-quality boron nitride thin films using chemical vapor deposition (CVD). The researchers used a mixture of boron trifluoride (BF3) and ammonia (NH3) gases as precursors to deposit BN thin films on sapphire substrates. The resulting BN films were highly crystalline and had a thickness of about 50 nm. The researchers also investigated the optical and electrical properties of the BN films and found them to be very promising for optoelectronic
