We present a microwave realization of finite tight-binding graphene-like structures. The structures are realized using discs with a high index of refraction. The discs are placed on a metallic surface while a second surface is adjusted atop the discs, such that the waves coupling the discs in the air are evanescent, leading to the tight-binding...

In this work, crack statistics are developed for MOCVD-grown 12 μm thick GaN on patterned Si substrate for different sizes, trench widths and trench heights of the mesas. Optical microscope is used to obtain the percentage ofcracked mesas in order to develop the crack statistics. The crack statistics show that the size and the trench height of...
