This Small Business Technology Transfer (STTR) Phase I project supports the development of ultra-fast ( 1 ns) response Transient Voltage Surge Suppression (TVSS) devices to protect the power infrastructure. Fine nickel particle (~ 50-150 micrometer) samples will be nano-coated by Atomic Layer Deposition (ALD) with alumina (Al2O3) (10, 7.5, 5, 2.5, and 1.5 nm thick Al2O3 coating), providing novel Metal Insulating Varistor (MIV) particles having metallic surfaces separated by insulative gaps on the order of atomic dimensions. These novel MIV particles will be embedded in coaxial prototype devices and pulse tested with thrust regime voltages up to of 20 kV. The Particle-ALDTM nano-coating process will be scaled-up and 1 kg of powder will be produced to provide samples for partner's devices. The losses in the US to high voltage surges exceed $26 billion annually. High voltage surges result from electrostatic discharges, high power microwaves, power line switching transients, lightning strikes, and potentially EMP. One possible method for handling the electrical overstresses is through the development of quantum tunneling MIVs as proposed here. Other device markets that could benefit from such functionalized fine powders include microelectronics, defense, medical, consumer products, and composite materials, among others.

该小型企业技术转让（STTR）第一阶段项目支持开发超快（1 ns）响应瞬态电压浪涌抑制（TVSS）器件，以保护电力基础设施。将通过原子层沉积（ALD）用氧化铝（Al 2 O3）（10、7.5、5、2.5和1.5 nm厚的Al 2 O3涂层）纳米涂覆细镍颗粒（~ 50-150微米）样品，提供具有由原子尺寸量级的绝缘间隙分隔的金属表面的新型金属绝缘压敏电阻（MIV）颗粒。这些新的MIV粒子将嵌入同轴原型设备和脉冲测试推力制度电压高达20千伏。Particle-ALDTM纳米涂层工艺将扩大规模，生产1 kg粉末，为合作伙伴的器械提供样品。美国每年因高压电涌造成的损失超过260亿美元。静电放电、高功率微波、电力线开关瞬变、雷击和潜在的电磁脉冲会导致高电压浪涌。处理电过应力的一种可能的方法是通过这里提出的量子隧穿MIV的发展。可以受益于这种功能化细粉的其他设备市场包括微电子、国防、医疗、消费品和复合材料等。
