Electric Conduction in a Single GaN Nanocolumn

Computational study of an InGaN/GaN nanocolumn light-emitting diode

Periodically arranged GaN nanocolumns for the application to visible nanocolumn emitters

The selective area growth (SAG) of GaN nanocolumns with the diameter less than 100 nm was carried out on GaN/sapphire templates through a careful initial nucleation process of nanocolumns at the mask opening. We got the success of the fabrication of orderly arrayed fine nanocolumns down to the diameter of 25 nm, as shown in Fig. 1, where the nanocolumn period was 100 nm. The growth of highly un...

Study of the Conduction Properties of the n GaN Cap Layer in GaN/InAlN/GaN E-HEMTs

Carrier transport in normally-off n GaN/InAlN/AlN/GaN high electron mobility transistors is studied using two-dimensional numerical device simulation. We focus on the n GaN cap layer, which is removed under the gate, and its contribution to drain current. Our simulation results show that despite the high doping density and relatively high carrier concentration in this layer, no significant tran...

Symmetry of two-terminal nonlinear electric conduction.

The well-established symmetry relations for linear transport phenomena cannot, in general, be applied in the nonlinear regime. Here we propose a set of symmetry relations with respect to bias voltage and magnetic field for the nonlinear conductance of two-terminal electric conductors. We experimentally confirm these relations using phase-coherent, semiconductor quantum dots.

Genetic determinants of cardiac (electric) conduction.

Sotoodehinia et al 1 investigated the role of common genetic variations (single nucleotide polymorphisms; SNPs) in determining QRS duration. The authors performed a meta-analysis of 14 genome-wide association studies of QRS duration in a total of 40 407 individuals (after adjustment for clinical variables) using a cut off of P 5 10 . The discovery phase was followed by a validation study consis...
