Silicon carbide

Manufacturing at the atomic scale is the next generation of the industrial revolution. Atomic and close-to-atomic scale manufacturing (ACSM) helps to achieve this. Atomic force microscopy (AFM) is a promising method for this purpose since an instrument to machine at this small scale has not yet been developed. As the need for increasing the number of electronic components inside an integrated circuit chip is emerging in the present-day scenario, methods should be adopted to reduce the size of connections inside the chip. This can be achieved using molecules. However, connecting molecules with the electrodes and then to the external world is challenging. Foundations must be laid to make this possible for the future. Atomic layer removal, down to one atom, can be employed for this purpose. Presently, theoretical works are being performed extensively to study the interactions happening at the molecule–electrode junction, and how electronic transport is affected by the functionality and robustness of the system. These theoretical studies can be verified experimentally only if nano electrodes are fabricated. Silicon is widely used in the semiconductor industry to fabricate electronic components. Likewise, carbon-based materials such as highly oriented pyrolytic graphite, gold, and silicon carbide find applications in the electronic device manufacturing sector. Hence, ACSM of these materials should be developed intensively. This paper presents a review on the state-of-the-art research performed on material removal at the atomic scale by electrochemical and mechanical methods of the mentioned materials using AFM and provides a roadmap to achieve effective mass production of these devices.

Silicon carbide (SiC) is emerging rapidly in novel photonic applications thanks to its unique photonic properties facilitated by the advances of nanotechnologies such as nanofabrication and nanofilm transfer. This review paper will start with the introduction of exceptional optical properties of silicon carbide. Then, a key structure, i.e., silicon carbide on insulator stack (SiCOI), is discussed which lays solid fundament for tight light confinement and strong light-SiC interaction in high quality factor and low volume optical cavities. As examples, microring resonator, microdisk and photonic crystal cavities are summarized in terms of quality (Q) factor, volume and polytypes. A main challenge for SiC photonic application is complementary metal-oxide-semiconductor (CMOS) compatibility and low-loss material growth. The state-of-the-art SiC with different polytypes and growth methods are reviewed and a roadmap for the loss reduction is predicted for photonic applications. Combining the fact that SiC possesses many different color centers with the SiCOI platform, SiC is also deemed to be a very competitive platform for future quantum photonic integrated circuit applications. Its perspectives and potential impacts are included at the end of this review paper.

Particularly, high-quality SiC single crystal produced by solution growth at a considerable rate has been reported in recent years, SiC bulk growth in the liquid phase requires a lower temperature than that of the sublimation or deposition process, and it demonstrates excellence in producing P-type SiC substrates (Table 3) [33,34] .

The third-generation semiconductor silicon carbide (SiC) has the characteristics of the wide band gap, high electric breakdown voltage, large saturated drift velocity, and high thermal conductivity, which are favorable for power devices under high-voltage, high temperature, and high-frequency scenarios [1,2] . Automotive applications are expected to remain a primary market for SiC power segments since they are one of the main drivers of the total power electronics market. The overall market for SiC devices is expected to exceed US$2.5 billion by 2025, with a compound annual
