摘要：
Large-grain-sized polycrystalline diamond films are fabricated by electron assisted chemical vapor deposition. A pure SP3 carbon bond in the cubic lattice structure is confirmed by Raman spectrum analysis. The grain size is on the order of several hundreds of mu m or larger. Interlaced-finger electrodes are imprinted onto a 6 x 6 mm(2) x 500 mu m film to fabricate the x-ray detector. The width of every finger is 25 mu m, and the distance between nearby fingers is 25 mu m. Strong x ray irradiates when a pulsed current flows through a double-layer nested tungsten wire array in the Z-pinch. This ...
