چکیده
The influence of the thermomechanical effects on optical properties germanium microstructures is investigated. Finite element method (FEM) calculations allow a complete spatial assessment mechanical deformations induced by silicon nitride (SiN) stressor layer deposited Ge micropillars. Simulated strain maps are confirmed experimental obtained Raman spectroscopy. theoretical investigation strain‐dependent band structure, including presence gradient along longitudinal direction, exploited to fully capture photoluminescence spectroscopy experiments. Finally, joint effect temperature and fundamental bandgap also quantified.

Tensile-strained germanium microdisk electroluminescence.
We report room temperature electroluminescence of tensile-strained germanium microdisks. The strain is transferred into the microdisks using silicon nitride stressors. Carrier injection is achieved with Schottky contacts on n-type doped germanium. We show that a biaxial tensile-strain up to 0.72% can be transferred by optimizing the carrier injection profile. The transferred strain is measured ...
متن کاملTheoretical Investigation of Biaxially Tensile-Strained Germanium Nanowires
We theoretically investigate highly tensile-strained Ge nanowires laterally on GaSb. Finite element method has been used to simulate the residual elastic strain in the Ge nanowire. The total energy increment including strain energy, surface energy, and edge energy before and after Ge deposition is calculated in different situations. The result indicates that the Ge nanowire on GaSb is apt to gr...
متن کاملOptical gain in single tensile-strained germanium photonic wire.
We have investigated the optical properties of tensile-strained germanium photonic wires. The photonic wires patterned by electron beam lithography (50 μm long, 1 μm wide and 500 nm thick) are obtained by growing a n-doped germanium film on a GaAs substrate. Tensile strain is transferred in the germanium layer using a Si₃N₄ stressor. Tensile strain around 0.4% achieved by the technique correspo...
متن کاملAnalysis of Hole Transport in Arbitrarily Strained Germanium
Full-band Monte Carlo simulations are performed to study the properties of hole transport in bulk Germanium under general strain conditions. The band structures are calculated with the empirical non-local pseudopotential method. For Monte Carlo simulations acoustic and optical phonon scattering as well as impact ionization are taken into account. Results for biaxially strained Ge grown on a [00...
متن کاملTensile-strained growth on low-index GaAs
We present a comparative study of the growth of tensile-strained GaP on the four low-index surfaces of GaAs: (001), (110), (111)A, and (111)B. For each surface orientation we outline the growth conditions required for smooth GaAs homoepitaxy. We are able to predict the resulting surface morphology when GaP is deposited onto these four GaAs surfaces by considering the influence of surface orient...
