We have templated Cu(100) surfaces with self-assembled arrays of atomic nitrogen islands and then used these islands as masks for Co growth. This method of nanolithography enables the creation of Co dot arrays with dot densities 4×1012 cm−2 (27 teradots/in.2). Adjusting the nitrogen coverage also enabled the creation of arrays of Co lines spaced 10 nm (0.01 μm) apart.

This study uses survey methodology to examine correlates of fear of crime among men and women to discern the unique impact of risk perception, victimization, vicarious victimization, and fear of sexual harm on fear of crime. Recently, scholars have begun to examine fear separately by gender, which is vital given the unique experiences men and women have with fear and victimization. We examine two different types of fear of crime to determine whether the effects of these correlates differ by crime type across gender. Results suggest that fear of sexual harm and risk perception are the most important indicators of fear of crime for both genders; sexual harm fear is particularly impactful for female fear of violence. Race and ethnicity also have interesting impacts for male fear of violent crime because racial and ethnic minorities indicate more fear of violent crime than White males. The findings illustrate how imperative it is to continue to examine fear of specific types of crime as well as distinguish fear by gender.

We demonstrate the ability to use scanning tunneling microscopy to create nanometer-scale pits on Ag films grown on Cu(100) substrates. Atomic resolution images show that the Ag structures are intact within these pits. We also demonstrate how we can selectively modify segments of Ag nanowire arrays grown on atomic nitrogen modified Cu(100) surfaces.

We demonstrate, using scanning tunneling microscopy, that the growth of Co onto Cu͑110͒ surfaces can be dramatically altered by first terminating the Cu͑110͒ surface with an atomic nitrogen-induced (2ϫ3) structure. Co growth onto such surfaces results in the formation of ordered arrays of Co nanowires. These results are contrasted with Co growth on clean Cu͑110͒ surfaces and suggest that the N termination also prevents the diffusion of Cu atoms into the Co layers.
