Resistance networks as a model for conduction on the nano-scale
(University of Missouri--Kansas City, 2011-05-13)
In this thesis, we calculate transport properties of amorphous materials in one,
two, and three dimensions. We take into account site disorder, manifest as a random
variation of the locations of atomic species. We employ ...
Transport Characteristics of Amorphous Semiconductors in the Dilute Carrier Regime: A Variable Range Hopping Treatment
(University of Missouri--Kansas City., 2011-01-20)
We survey the analytical methods which are used to find the conductivity of amorphous solids as a function of temperature, specifically the work done by N. F. Mott and Apsley et al. and we point out the problems with ...
Electronic structure and optical properties of layered ternary transition-metal carbides and nitrides
(University of Missouri--Kansas City, 2011-05-20)
The electronic structure and optical properties of Ti3AC2 (A=Al, Si, Ge), Ti2AC
(A=Al, Ga, In; Si, Ge, Sn; P, As; S), Ti2AlN, M2AlC (M=V, Nb, Cr) and Tan+1AlCn (n=1~4)
have been studied using first-principles orthogonalized ...
Exploratory identification of introductory algebra-based physics success factors
(University of Missouri-Kansas City, 2011-06-08)
The field of physics suffers from low student matriculation through its degree programs as well as being viewed as being abstract, complicated, and incomprehensible by students enrolled in introductory courses. A study was ...
Current sensing atomic force microscopy study of aging mechanism of the nafion membranes due to thermal annealing
(University of Missouri--Kansas City, 2011-09-14)
Proton transport properties of Nafion 212 and Nafion 115 membranes have been
studied using current sensing atomic force microscopy to reveal changes of the ionic domains
and the local ionic conductivity distribution in ...
