We experimentally demonstrate an efficient coupler between a silicon waveguide and a hybrid plasmonic waveguide for the wavelength range 1460-1540 nm. Such compact, efficient plasmonic couplers provide a promising platform for integrated photonic circuits.
Preconcentration method is usually used in gas chromatographic analysis system for gas condensation in detection of wound pathogen and measurement of low concentrations of odorous components. Preconcentrators (traps) consist of a stainless-steel or glass tube packed with granular adsorbent material. Desorption occurs when a current is passed through the stainless steel tube or through a metal wire...
We investigate the impact of structure relaxation on the upper performance of a silicon nanowire metal-oxide-semiconductor field-effect-transistor (MOSFET) with small diameter employing a semiclassical transport model to calculate its ballistic I-V characteristics. For wires along the lang110rang axis and 1 nm diameter, structure relaxation induces large changes in the bond length of silicon atoms...
Excessive power supply noise can affect path delay and cause overkill during delay test. This paper presents low-cost noise models for fast power supply noise analysis and timing analysis considering noise impact. Our prior work only considered array-bond chips. This work proposes a noise analysis methodology that can be applied to wire-bond chips as well as array-bond chips. Experiments were performed...
Using a semi-empirical, sp3d5s* tight-binding approach and a 'top-of-the-barrier' ballistic FET model, we report full-band simulations of ballistic Si and Ge nanowire FETs with various channel orientations and wire diameters. We find that the nanowire FET performance displays a strong orientation and diameter dependence, and [110] is the optimum orientation for both Si and Ge nanowire FETs
