Distribution of conductance for Anderson insulators: A theory with a single parameter
We obtain an analytic expression for the full distribution of conductance for a strongly disordered threedimensional conductor within a perturbative approach based on transfer-matrix formulation. Our results confirm the numerical evidence that the log-normal limit of the distribution is not reached even in the deeply insulating regime. We show that the variance of the logarithm of the conductan...
متن کاملConductance distribution in 3 D Anderson insulators : de - viation from log - normal form
– Metal-insulator transitions and other electronic transitions. PACS. 72.10.-d – Theory of electronic transport; scattering mechanisms. Abstract. – We show how a recent proposal to obtain the distribution of conductances in three dimensions (3D) from a generalized Fokker-Planck equation for the joint probability distribution of the transmission eigenvalues can be implemented for all strengths o...
متن کاملConductance of T-shaped Graphene nanodevice with single disorder
Disordered T-shaped graphene nanodevice (TGN) was designed and studied in this paper. We demonstrated the intrinsic transport properties of the TGN by using Landauer approach. Knowing the transmission probability of an electron the current through the system is obtained using Landauer-Buttiker formalism. The effects of single disorder on conductance, current and on the transport length scales a...
متن کاملA Two-parameter Balakrishnan Skew-normal Distribution
In this paper, we discuss a generalization of Balakrishnan skew-normal distribution with two parameters that contains the skew-normal, the Balakrishnan skew-normal and the two-parameter generalized skew-normal distributions as special cases. Furthermore, we establish some useful properties and two extensions of this distribution.
متن کاملA parameter-tuned genetic algorithm for vendor managed inventory model for a case single-vendor single-retailer with multi-product and multi-constraint
This paper develops a single-vendor single-retailer supply chain for multi-product. The proposed model is based on Vendor Managed Inventory (VMI) approach and vendor uses the retailer's data for better decision making. Number of orders and available capital are the constraints of the model. In this system, shortages are backordered; therefore, the vendor’s warehouse capacity is another limitati...
