    • The invention relates to an electrode having a nano-hollow array on the surface thereof, the nano-hollow array comprising a plurality of nano-pores or nano-balls, each pore having a diameter of less than 500 nm, formed by a process comprising depositing a uniform metal film on the electrode structure surface at a rate of 2 Å per second or less, annealing the metal film under rapid anneal conditions at a temperature within about 100 degrees of the melting point of the metal film and without subjecting the metal film to a temperature ramp-up to create metal droplets, and anodizing and over-anodizing the metal droplets in the presence of an anodization agent for the metal at from 20 to 200 volts at 0.1 to 2 amps to create nano-pores in the metal droplets or nano-balls to, creating increased surface area and increased electric field around the electrode which enhances speed of fill gas ionization.
    • 本发明涉及一种在其表面上具有纳米中空阵列的电极,所述纳米中空阵列包括多个纳米孔或纳米球,每个孔具有小于500nm的直径,其形成方法包括 以每秒2埃的速度在电极结构表面上沉积均匀的金属膜,在金属膜的熔点约100度的温度下在快速退火条件下退火金属膜, 到达温度上升以产生金属液滴,以及在0.1至2安培处的20至200伏特的金属阳极氧化剂存在下阳极氧化和过度阳极化金属液滴以在金属液滴中产生纳米孔 或纳米球,从而在电极周围产生增加的表面积和增加的电场,这增强了填充气体电离的速度。
