Abstract: Convergent nanofabrication and nanoassembly methods are disclosed. Molecules and/or nanostructures are bound to supported binding tools and manipulated to bond together in desired locations and orientations to yield desired precise structures. Methods for precise fabrication of materials including diamond, graphene, nanotube, ?-SiC (and precise modifications thereof, e.g. color centers for quantum computation and information processing and storage), halite structured materials including MgO, MgS, TiC, VN, ScN, precisely Mn doped ScN, NbN, HfC, TaC, HfxTayC, and metals, and graphenoid structures for photovoltaic devices are disclosed. Systems disclosed performing these methods can fabricate systems with similar capabilities, enabling allo- or self-replication, and have capabilities including: conversion and storage of energy; obtainment and processing of matter from abundant environmental sources including on other planets and fabrication of desired articles using same; converting wind power (esp.
