Ab initio density functional theory study on the atomic and electronic structure of GaP/Si(001) heterointerfaces

The atomic and electronic band structures of GaP/Si(001) heterointerfaces were for the abrupt and the lowest-energy heterointerface structures. The distinct features in the heterointerface electronic s...

GaP-on-Si(100) heterointerfaces studied in situ

We give an overview on how we combine optical in situ RAS during industrially scalable growth processes by MOVPE with electron-based in vacuo surface science analytics in order to study the GaP/Si(001) heterointerface formation and its atomi...

Time-resolved in situ spectroscopy during formation of the GaP/Si(100) heterointerface

Though III?V/Si(100) heterointerfaces are essential for future epitaxial high-performance devices, their atomic structure is an open historical question. Benchmarking formation of surfaces and of the heterointerface. A terr...

Identifying Ionic and Electronic Charge Transfer at Oxide Heterointerfaces

heterointerfaces crucially depend on their ionic constitution and defect structure: ionicThe ability to tailor oxide heterointerfaces has led to novel properties in low a thermodynamic balance of ionic and electronic s...

A combined in situ RAS, in vacuo XPS and ab initio DFT study of the GaP/Si(100) heterointerface

We study the preparation and atomi order of the buried GaP/Si(001) heterointerfaces in situ with RAS, XPS, and ab initio DFT. We demonstrate that preparation of almost single domain Si(001) substrate succeeds in suppressing anti-phase disord...

III/V-on-Si interfaces: optical in situ control, surface science and DFT

Pseudomorphic virtual GaP/Si substrates are attractive for III/V-on-Si integration for microelectronics, photovoltaics, and water-splitting. The heterointerface is of particular interest since its atomic and electronic structure hig...

Atomic and electronic structure of GaP/Si(111), GaP/Si(110), and GaP/Si(113) interfaces and superlattices studied by density functional theory

The atomic structure of GaP(111)/Si(111), GaP(110)/Si(110), and GaP(113)/Si(113) heterointerfaces was studied by ab initio calculations employing the density functional theory (DFT). Relative formation energies were computed for the...

GaP-on-Si heterointerfaces and quasisubstrate growth studied in situ during MOVPE

It was demonstrated how time-resolved RAS measurements enable to in situ monitor the GaP nucleation on Si. The GaP sublattice can be inverted by a 'rotation' of the Si dimers prior nucleation or more Ga-rich growth conditions. The impact of As on Si ...

Band bending at heterovalent interfaces: hard X-ray photoelectron spectroscopy of GaP/Si(0 0 1) heterostructures

GaP is a preferred candidate for the transition between Si and heterogeneous III-V epilayers as it is nearly lattice-matched to Si. Here, we scrutinize the atomic structure and electronic properties of GaP/Si(001) heterointerfaces u...

Electroluminescence in a semimetal channel at a single broken-gap heterointerface of type II.

The radiative recombination at the broken-gap p-GaInAsSb/p-InAs type-II interface was investigated in the temperature range of 4-100K.Two electroluminescence bands at 0.37 eV and 0.40 eV were observed. The first EL maximum was ascribed to recombinati...
