Blue emitting GaN-based light emitting diodes (LEDs) show a distinct spectral behavior with respect to temperature and injection current density. Operating LEDs with short current pulses of 500 ns provides a steady state situation, which allows inves

A nomenclature system is presented that can be applied to a range of spherical, tubular and planar structures. The starting point in this system is determined using semi-empirical calculations that establish the atomic charge of all species. This met

In this paper, it is reported that microwave synthesis techniques can be used to convert graphite powder and fluorinated graphite in different matrices to fullerenes (i.e., C60 and C70). The microwave approach allows for the quick, economical product

A number of studies show that chemical modification of the semiconductor–dielectric interface can be used to control the threshold voltage (Vth) of organic thin film transistors (OTFTs). A promising chemical functionality to achieve that are acidic

The coherence length of electromagnetic waves created by different light sources is a largely overlooked parameter. Since the coherence length and its spectral distribution are essential for the entire field of interference, ranging from unintended d

The nature and quality of artificial lighting are becoming more and more recognized and debated issues concerning their impact on comfort, well-being and even human’s health (chronobiology). Therefore, the target must be to emulate natural (sun) li
