Nonlinear Photocurrent Spectroscopy and Polarization-Tunable Shift Current in the Layered Semiconductor
Alexander M. Blackston, Md Kazi Rokunuzzaman, Ryan P. Siebenaller +4
The class of layered metal thiophosphates and selenophosphates are emerging as promising candidates for non-linear photonic and optoelectronic applications. Here we report one-phot…
Dislocation-templated antiferromagnetic domains in epitaxial NiO
Alexandra Fonseca Montenegro, Justin Michel, Fengyuan Yang +1
Controlling antiferromagnetic domains is essential for spintronics, yet predictable manipulation remains challenging due to their lack of net magnetization. Here, we utilize scanni…
Cryogenically Enhanced Laser-Induced Amorphous Phase Transitions in Crystalline Silicon
Conrad Kuz, Andy Lee, Shashu Tomar +6
Amorphization of silicon is crucial to applications in photonics, microelectronics and solar cell technologies. Ultrafast lasers have been used to generate amorphous silicon from c…
Photoluminescence excitation spectroscopy of quantum wire-like dislocation states in ZnS
Alexander Blackston, Alexandra Fonseca Montenegro, Sevim Polat Genlik +2
Recent \textit{ab initio} calculations predict 1D dispersive electronic bands confined to the atomic scale cores of dislocations in the wide bandgap (3.84 eV) semiconductor ZnS. We…
Epitaxially-stabilized growth of wüstite FeO on 4H-SiC
Faisal Kimbugwe, Marzieh Baan, Alexandra Fonseca Montenegro +2
Iron(II) monoxide (FeO) is thermodynamically stable in the halite (wüstite) structure only at elevated temperatures in a typically non-stoichiometric, Fe-deficient, FeO for…
A common origin of photoplastic and electroplastic effects in ZnS
Alexandra Fonseca Montenegro, Sevim Genlik Polat, Md Mohsinur Rahman Adnan +2
Dislocation motion--the atomic-scale mechanism of crystal plasticity--governs the strength and ductility of materials. In functional materials, external stimuli beyond mechanical s…
Origin of the Anisotropic Beer-Lambert Law from Dichroism and Birefringence in -GaO
Md Mohsinur Rahman Adnan, Mathias Schubert, Roberto C. Myers
The anisotropic optical absorption edge of -GaO follows a modified Beer-Lambert law having two effective absorption coefficients. The absorption coefficient of linearly…
The Origin of Photoplasticity in ZnS
Sevim Polat Genlik, Roberto C. Myers, Maryam Ghazisaeidi
ZnS is a brittle material but shows extraordinary plasticity during mechanical tests performed in complete darkness. This phenomenon is known as the photoplastic effect, whose unde…
Log-normal glide and the formation of misfit dislocation networks in heteroepitaxial ZnS on GaP
Alexandra Fonseca Montenegro, Marzieh Baan, Maryam Ghazisaeidi +2
Scanning electron microscopy (SEM) based electron channeling contrast imaging (ECCI) is used to observe and quantify misfit dislocation (MD) networks formed at the heteroepitaxial…
