We report on the electrical in-situ characterisation of organic thin film transistors under high vacuum conditions. Model devices in a bottom-gate/bottom-contact (coplanar) configuration are electrically characterised in-situ, monolayer by monolayer (ML), while the organic semiconductor (OSC) is evaporated by organic molecular beam epitaxy (OMBE). Thermal SiO2 with an optional polymer interface...

Sputtering of organic overlayers has been modeled using molecular dynamics computer simulations. The investigated systems are composed of benzenemolecules condensed into one, two and three layers on anAg{1 1 1} surface. The formed organic overlayers were bombarded with 4 keV Ar projectiles at normal incidence. The development of the collision cascade in the organic overlayer was investigated. T...

Eucalyptus obliqua, the most widespread timber tree in Tasmania, is a pioneer after fire which can eliminate the organic layer of forest soil, exposing the underlying mineral soil. We compared seedling growth, mycorrhiza formation, and mineral nutrient limitation in organic layer vs. mineral soil. We grew E. obliqua seedlings separately in pots of organic layer and mineral soil in a glasshouse....

Organic solar cells have advantages over the traditional inorganic solar cells. The flexibility and light-weight of an organic solar device lead to novel deployment unattainable by inorganic solar devices. There is a wide range of materials that can be used to fabricate an organic solar cell with many suitable conducting polymers and small molecules. The large number of appropriate materials me...

In this paper, we used the time-of-flight (TOF) of a charge packet, that injected by a voltage pulse to calculate the drift velocity and mobility of holes in organic semiconducting polymers. The technique consists in applying a voltage to the anode and calculating the time delay in the appearance of the injected carriers at the other contact. The method is a simple way to determine the charge t...

the aim of this study was to assess the conversion of forest to vineyard on different physical pools of organic matter in zrebar lake watershed. soil samples were collected from the two major land use types including forest and vineyard land at 0-30; 30-60, and 60-90-cm depths. in each land use, different soc fractions were measured. according to the results of size fractionation of organic car...

The synthesis and application of new organic materials, nanostructured, for developing technology based on organic devices, have been the main focus of the scientific community. In recent years, the first polymeric electronics products have entered the market (organic semiconductor materials) and there are some electrochromic devices among them that have been called smart windows, once they con...

Organic light-emitting devices (OLEDs) have attracted lots of attentions and have been subjects of intensive studies due to their great potential for plat panel display and solid state illumination applications. In this paper, we designed a new type of ultra-thin non doped organic blue electrophosphorescent devices of based on Firpic. We also studied that the impact of object layer thickness fo...
