Silicon used for electronics has a cubic crystal lattice, which makes the material unsuitable for photonics applications. A method for producing germanium and silicon-germanium alloys that have hexagonal lattices offers a solution. ...
Hydrogen storage and utilization are the technologies to achieve carbon-neutral energy systems with renewable energy sources. Among the various materials that have been investigated, complex hydrides are a material exhibiting high gravimetric hydrogen dens ...
The Cover Feature shows the application of a pyrrolidinium-based ionic liquid with a borohydride anion to simultaneously capture and reduce large amounts of CO2. The ionic liquid cation interacts with CO2, allowing the borohydride to fix and reduce it to t ...
The reaction of the Rh-7(CO)(16) cluster anion with Ge2+ salts, in different stoichiometric ratios and under different atmospheres, leads to the formation of new heterometallic Rh-Ge clusters, representing the first known examples of Rh carbonyl comp ...
Recently, several research groups have reported the growth of germanene, a new member of the graphene family. Germanene is in many aspects very similar to graphene, but in contrast to the planar graphene lattice, the germanene honeycomb lattice is buckled ...
Similar to alane in alanates, borane species are assumed to be the mass transport intermediate in the hydrogen storage reaction MH + B + 3/2H2 MBH4 with M = Li and Na. One possible substep of this reaction is the interaction of diborane with the alkali hyd ...
Tunnel FETs are the most promising ultra low power devices due to their potential of steeper subthreshold slopes and capability of using very low drive voltages. Switching is based on quantum mechanical band to band tunneling and no longer on thermal emiss ...
Band offsets of the Ge/GeO2 interface are calculated through a hybrid density functional scheme. We first generate a model of disordered GeO2 through ab initio molecular dynamics to describe the oxide component. For addressing the interface, we then consid ...
We describe a new method for the solvent-free synthesis of borohydrides at room temperature and demonstrate its feasibility by the synthesis of three of the most discussed borohydrides at present: LiBH4, Mg(BH 4)2 and Ca(BH4)2. This new gas-solid mechanoch ...
In the context of the diminishing fossil energy resources and global warming, much research is focused on sustainable energy sources. The research that is presented in this thesis falls in this category as it contributes to the development of a device that ...
