Field emission from non-uniform carbon nanotube arrays [PDF]

open access: yesNanoscale Research Letters, 2013
Regular arrays of carbon nanotubes (CNTs) are frequently used in studies on field emission. However, non-uniformities are always present like dispersions in height, radius, and position. In this report, we describe the effect of these non-uniformities in the overall emission current by simulation.

Kantians Defy the Economists’ Mantra of Uniform Pigovian Emissions Taxes [PDF]

open access: yesSSRN Electronic Journal, 2020
This paper analyzes the efficient emissions taxation in economies with individuals who are morally motivated to reduce their emissions footprint. They are heterogenous with respect to their morality and their consumption preferences. We distinguish between the concepts of moral and conventional utilitarian (= material) welfare. The materially efficient
