研究了厚度分别为120或200 μm、30 μm和5 μm的Al 2 O3、BN和BaTiO 3介电膜的镍屏/电介质/镍微放电器件的电（V-I）特性、辐射效率和寿命，这些器件的总厚度小至<100 μm，圆柱形微通道直径为50-150μm。 这些器件通过溶胶-凝胶工艺或胶体沉积制造，并在300至1200 Torr（300 K）的Ne气体压力下工作，其工作电压低至1093V（100 µm直径）。 BaTiO 3器件），并表现出优异的稳定性和寿命。在100小时的连续操作之后，在700Torr Ne（静态气体填充）和100 V下操作的Ni屏/30 μm BN/Ni装置产生其初始辐射输出的约98%。
The electrical (V-I) characteristics, radiative efficiencies, and lifetimes of Ni screen/dielectric/Ni microdischarge devices, having overall thicknesses as small as <100 µm and cylindrical microchannels 50–150 µm in diameter, are investigated for Al2O3, BN, and BaTiO3 dielectric films that are 120 or 200 µm, 30 µm, and 5 µm in thickness, respectively. Having dielectrics fabricated by sol–gel processes or colloidal deposition and operated with Ne gas pressures between 300 and 1200 Torr (300K), these devices operate at voltages as low as ∼93 V (100 µm dia. BaTiO3 device), and exhibit exceptional stability and lifetimes. After 100 h of continuous operation, a Ni screen/30 µm BN/Ni device operating in 700 Torr Ne (static gas fill) at 100 V produces ∼98% of its initial radiant output.
