They are replacing Si devices due to the higher performance of SiC material.
Introduction Higher performance of SiC material [1] has led to the gradual replacement of silicon MOSFETs with SiC devices in many applications.
SiC material has a higher bandgap and it can stand higher critical electric field than silicon.

Diamond-like-carbon (DLC) is a generic term for a class of materials able to be synthesized by a variety of well-established routes, leading to phases that are diamond-like, with hardness and other mechanical properties being also comparable to those of crystalline diamond [13].
The ability to pattern DLC combined with its inherent durability also makes this material an ideal candidate for molding technologies.

The wettability behavior of superhydrophobic surfaces can be transformed to achieve Wettability switching under specific conditions: optical, magnetic, mechanical, chemical, thermal [14], Silicon is probably the most important material for applications such as sensors and optoelectronic devices. surfaces have been created by modifying with hydrophobic materials on nanostructured Si surface prepared by metal-assisted chemical etching (MaCE) [15,16,17], the VLS growth technique [18,19]or hierarchically double-scale (micro- and nanoscale) textured silicon surface formed by using femtosecond laser pulses in SF6 [20], a nonlithographic top-down electrochemical approach [21], deep reactive ion etching and galvanic etching [22].
Experiment The materials used for experiments were boron doped p-type single-crystalline with resistivity of 1-3 Ω cm.

Therefore, some other wide band gap semiconductor materials, e.g.
On the one hand, ZnO is a wide direct band gap semiconductor materials with 3.2 eV, the band gap is the same as TiO2.
Accordingly, ZnO as the photoelectrodes used in DSCs, has been a hot research topic in energy materials.

So the composite material elongation at break elevated.
When the fumed silica is too much, it united in the composite material, so that the material elongation at break decreased.

Therefore the development of new membrane materials for PEM fuel cells is nowadays an important task of both science and technology.
Organic-silicon composite materials combine the desired characteristics of polymeric materials (e.g., flexibility, ductility, and processability) and inorganic material (e.g., heat resistance, retention of mechanical properties at high temperature, and low thermal expansion) [6,7].
