In situ electrical probing and bias-mediated manipulation of dielectric nanotubes in a high-resolution transmission electron microscope
Abstract
<p>Boron nitride nanotubes filled with magnesium oxides [MgO, MgO <sub>2</sub>] and/or hydroxide [Mg(OH) <sub>2</sub>] are electrically probed and delicately manipulated inside a 300 kV JEOL-3000F high-resolution transmission analytical electron microscope equipped with a side-entry "Nanofactory Instruments" piezoholder. At a low bias the nanotubes demonstrate truly insulating behavior. At a high bias of ±30 V they show reversible breakdown current of several dozens of nA. Under 300 kV electron beam irradiation the nanotubes are positively charged that allows us to perform on-demand manipulation with them through tuning of polarity and/or value of a bias voltage on a gold counterelectrode from -140 to +140 V, owing to the prominent electrostatic nanotube-electrode interactions.</p>
