美国“应用物理快报”1970年1月(Appl.Phys.Lett.16(1),P.40)刊登了法国一实验室的一篇研究简报,报导氧化镍薄膜在室温下有开关和负阻效应。据说,这种效应是可逆的,并且有相当好的重复性。 先在真空中(<10~(-6)mm)把镍蒸发到300℃的云母或玻璃衬底上,然后在400℃的干燥氧气中将之完全转变为NiO薄膜。膜是多晶的,颗粒大小为1000埃数 Applied Physics Letters, January 1970 (Appl. Phys. Lett. 16 (1), p. 40) published a research note from a French laboratory reporting that nickel oxide films have switching and negative resistance at room temperature effect. It is said that this effect is reversible and has fairly good repeatability. Nickel was first vaporized to a mica or glass substrate at 300 ° C in vacuum (<10 -6 mm) and then completely converted into a NiO film in dry oxygen at 400 ° C. The film is polycrystalline with a particle size of 1000 angstroms
