A new method for the parallel fabrication of carbon nanotube (CNT) electronic devices is described. Self-assembly via magnetic entrapment exploits magnetic fields generated within micrometer- or nanometer-scale devices for the controlled deposition of susceptible species onto predefined contacts (see Figure). The fabrication of carbon nanotube field-effect transistors (CNFETs) using this method are discussed.
