Selective area epitaxy of GaAs films using patterned graphene on Ge
Zheng Hui Lim, Sebastian Manzo, Patrick J. Strohbeen +3
We demonstrate selective area epitaxy of GaAs films using patterned graphene masks on a Ge (001) substrate. The GaAs selectively grows on exposed regions of the Ge substrate, for g…
Effect of Buffer Termination on Intermixing and Conductivity in LaTiO/SrTiO Heterostructures Integrated on Si(100)
Tongjie Chen, Kamyar Ahmadi-Majlan, Zheng Hui Lim +3
The control of chemical exchange across heterointerfaces formed between ultra-thin functional transition-metal oxide layers provides an effective route to manipulate the electronic…
Pinhole-seeded lateral epitaxy and exfoliation of GaSb films on graphene-terminated surfaces
Sebastian Manzo, Patrick J. Strohbeen, Zheng-Hui Lim +3
Remote epitaxy is a promising approach for synthesizing exfoliatable crystalline membranes and enabling epitaxy of materials with large lattice mismatch. However, the atomic scale…
A multi-stop time-of-flight spectrometer for the measurement of positron annihilation-induced electrons in coincidence with the Doppler-shifted annihilation gamma photon
V. A. Chirayath, R. W. Gladen, A. D. McDonald +12
Here we describe an advanced multi functional, variable-energy positron beam system capable of measuring the energies of multiple positron-induced electrons in coincidence with the…
Charge transfer and tunable built-in electric fields across semiconductor-crystalline oxide interfaces
Zheng Hui Lim, Nicholas F. Quackenbush, Aubrey Penn +10
Built-in electric fields across heterojunctions between semiconducting materials underpin the functionality of modern device technologies. Heterojunctions between semiconductors an…
Interfacial Structure of SrZrTiO films on Ge
Tongjie Chen, Kamyar Ahmadi-Majlan, Zheng Hui Lim +4
The interfacial structure of SrZrTiO films grown on semiconducting Ge substrates are investigated by synchrotron X-ray diffraction and first-principles density fu…
