    摘要: A method of preparing tunable inorganic patterned nanofeatures by infiltration of a block copolymer scaffold having a plurality of self-assembled periodic polymer microdomains. The method may be used sequential infiltration synthesis (SIS), related to atomic layer deposition (ALD). The method includes selecting a metal precursor that is configured to selectively react with the copolymer unit defining the microdomain but is substantially non-reactive with another polymer unit of the copolymer. A tunable inorganic features is selectively formed on the microdomain to form a hybrid organic/inorganic composite material of the metal precursor and a co-reactant. The organic component may be optionally removed to obtain an inorganic features with patterned nanostructures defined by the configuration of the microdomain.

    摘要: A method of preparing a superconducting thin film of niobium silicide using atomic layer deposition (ALD) where the superconducting critical temperature of the film is controllable by modulating the thickness of the thin film. The film is formed by exposing a substrate within an ALD reactor to alternating exposures of a niobium halide (NbQx) and a reducing precursor, for example, disilane (Si2H6) or silane (SiH4). A number of ALD cycles are performed to obtain the film thickness and establish the desired superconducting critical temperature between 0.4 K and 3.1 K.
