Conductivity varies with grain size of GDC films due to the grain boundary space charge effect, the smaller the grain size, the higher the conductivity and vice versa.

晶界空间电荷效应导致GD C薄膜电导率随晶粒尺寸而变化，晶粒尺寸越小，电导率越大。

The boundary between the two areas acts as a wall, capable of reflecting a guided EM wave on the graphene much like one would in a three dimensional space.

两个区域的边界就像是一堵墙，能反射被引导的电磁波； 这和三维空间中的墙是类似的。

"If the Wright brothers were starting out today they'd never get off the ground, " fumes Ky Michaelson, who spent two years dickering with bureaucrats at an offshoot of the FAA to get a license to launch to 390, 000 feet, well past the boundary zone between the Earth's atmosphere and space.
