We report a material-dependent critical temperature for ion beam sculpting of nanopores in amorphous materials under keV ion irradiation. At temperatures below the critical temperature, irradiated pores open at a rate that soon saturates with decreasing temperature. At temperatures above the critical temperature, the pore closing rate rises rapidly and eventually saturates with increasing tempe...

Given the wide topic coverage and the sometimes introductory character of the book, it is not helpful that only 21 bibliographic entries are provided for the entire book. The offer of a wider bibliography selection would significantly improve the usefulness of the book, since its topic diversity is likely to require for most readers additional reading on some of the topics.

Abstract Insulator-to-metal (I–M) transition is crucial for an intermediate-band (IB) photovoltaic material to suppress the non-radiative recombinations and improve its efficiency. Nevertheless, mechanism critical condition of I–M not clear yet. In this work, conditions in two types Si-based IB materials were studied by combining molecular dynamics simulations Landauer transmission calculations...

Bulk nanostructured materials are made from the assembly of octahedral PbSe nanocrystals. After thermal annealing, the artificial bulk demonstrates a large difference in behavior depending on the temperature, and a large variation of room-temperature resistivity of up to seven orders of magnitude. This variation originates from the high-indexed sharp edges of the octahedral nanocrystals. As the...
