Ferroelectric Epsilon-WO3 Nanoparticles and Its Bipolaron Driven Opto-electronic Properties at Room Temperature

Mohammad M. Rahaman, Jose Flores, Mohamed Y. Noor +6

A unique polymorph of binary tungsten trioxide, the epsilon phase of WO3, has non-centrosymmetric ferroelectric structure, typically stable below -43 degree C in bulk. We have stab…

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 anisotropic Beer-Lambert law in -GaO: Spectral and polarization dependent absorption and photoresponsivity

Md Mohsinur Rahman Adnan, Darpan Verma, Chris Sturm +2

Due to its low symmetry, -GaO exhibits a strongly anisotropic optical response. As a result, the absorption spectra change with the polarization state of the incomin…

Anisotropic excitonic photocurrent in -GaO

Darpan Verma, Md Mohsinur Rahman Adnan, Sushovan Dhara +3

Polarization dependent photocurrent spectra are measured on a (001) -GaO Schottky photodetector, where the linear polarization of light is rotated within the ab plan…

Spectral measurement of the breakdown limit of and tunnel ionization of self-trapped excitons and holes

Md M. Adnan, Darpan Verma, Zhanbo Xia +3

is an unusual semiconductor where large electric fields (~1-6 MV/cm) can be applied while still maintaining a dominant excitonic absorption peak below its ultra-wid…

Local Electric Field Measurement in GaN Diodes by exciton Franz-Keldysh Photocurrent Spectroscopy

Darpan Verma, Md Mohsinur Rahman Adnan, Mohammad Wahidur Rahman +2

The eXciton Franz-Keldysh (XFK) effect is observed in GaN p-n junction diodes via the spectral variation of photocurrent responsivity data that redshift and broaden with increasing…
