Molecules are promising candidates for electronic device components because of their small size, chemical tunability, and ability to self-assemble. A major challenge when building molecule-based devices is forming reliable molecular junctions controlling the electrical current through junctions. Here, we report a three-terminal junction that combines both form stable single-molecule via mechanically controllable break (MCBJ) technique shift energy levels molecule by gating. Using noncontact...

This paper solves the adaptive consensus problem for first-order linearly parameterized agents with completely nonidentical unknown high-frequency gain signs under directed graphs. A new class of Nussbaum-type function-based algorithms are proposed to handle adaptively and cooperatively. It is shown that if underlying topology a fixed graph strongly connected or switching topologies having jointly basis, can achieve asymptotic consensus. Finally, effectiveness verified by one simulation example.
Existing results on cooperative control of multiagent systems with unknown directions require that the underlying topology is either fixed a strongly connected graph or switching between different graphs. Furthermore, in most cases assumed to be balanced. This paper proposes new class nonlinear proportional-integral (PI) based algorithms relax these requirements and allow for unbalanced topologies having jointly basis. made possible single-integrator (SI) double-integrator (DI) agents...

Utilizing individual atoms or molecules as functional units in electronic circuits meets the increasing technical demands for miniaturization of traditional semiconductor devices. To be technological interest, these devices should high-yield, consume low amounts energy, and operate at room temperature. In this study, we developed nanodevices called quantized conductance atomic switches (QCAS) that satisfy requirements. The QCAS operates by applying a feedback-controlled voltage to...
