SiC devices are made from silicon carbide(SiC) wafers. So, here comes a question: how to obtain a silicon carbide wafer? Generally, a SiC wafer is cut from cylindrical SiC boules. As for the cutting process, methods for cutting silicon carbide ingots are introduced here.
A diamond [...]

Highlights
•Aberration-corrected TEM and EELS reveal structural and elemental profiles across GaAs/Si bond interfaces in wafer-bonded GaInP/GaAs/Si – multi-junction solar cells.
•Fluctuations in elemental concentration in nanometer-thick amorphous interface layers, including the disrubutions of light elements, are measured using EELS.
•The projected widths of the interface layers [...]

Limiting Efficiency
It has been well established that the limiting efficiency of single crystals falls at about 29% [Swanson] this limit was established in the seminal work by Tiedje. In figure 1 we can see this limiting efficiency [...]
