近日,普林斯顿大学和HP公司的研究人员联合展示了一种塑料和硅的薄膜体化合物。该化合物由普遍使用的塑料物质和少量的硅制成,可用以制造一次性的内存单元,存储数GB的信息,这样就以一种便宜的方式实现了数字信息的存储。 这种塑料聚合体被称为PEDOT(为该物质的化学名称的简写)。PEDOT在低电压状态下为导体,在更高的电压下就会变成半导体。科学家们在材料中加入金属丝(fuse),当在材料的特定区域上施加高电压时,烧断和未烧断的金属丝就永久地留下 Recently, Princeton University and HP researchers jointly demonstrated a thin film of plastic and silicon compounds. Manufactured from commonly used plastic materials and a small amount of silicon, this compound can be used to make disposable memory cells that store several gigabytes of information, saving digital information in a cheap way. This plastic polymer is called PEDOT (abbreviation for the chemical name of the substance). PEDOT is a conductor at low voltage and becomes a semiconductor at higher voltage. Scientists add a fuse to the material, leaving the blown and non-blown wires permanently when a high voltage is applied to a specific area of ​​the material
