Exceeding the Shockley-Queisser limit within the detailed balance framework
Marnik Bercx, Rolando Saniz, Bart Partoens +1
The Shockley-Queisser limit is one of the most fundamental results in the field of photovoltaics. Based on the principle of detailed balance, it defines an upper limit for a single…
Extended homologous series of Sn-O layered systems: a first-principles study
Kirsten Govaerts, Bart Partoens, Dirk Lamoen
Apart from the most studied tin-oxide compounds, SnO and SnO2, intermediate states have been claimed to exist for more than a hundred years. In addition to the known homologous ser…
Easily doped p-type, low hole effective mass, transparent oxides
Nasrin Sarmadian, Rolando Saniz, Bart Partoens +1
Fulfillment of the promise of transparent electronics has been hindered until now largely by the lack of semiconductors that can be doped p-type in a stable way, and that at the sa…
A new technique for the sp/sp characterisation of carbon materials
J. Titantah, D. Lamoen
We present a technique to determine the sp/sp ratio of carbon materials which is based on the electron energy-loss spectroscopy and which uses the theoretical spectrum of g…
Density functional theory calculations of the carbon ELNES of small diameter armchair and zigzag nanotubes: core-hole, curvature and momentum transfer orientation effects
J. T. Titantah, K. Jorissen, D. Lamoen
We perform density functional theory calculations on a series of armchair and zigzag nanotubes of diameters less than 1nm using the all-electron Full-Potential(-Linearised)-Augment…
