“Exploring Advanced Optoelectronic and Functional Devices
with Advanced Quantum- & Nano-structures and Materials”
Welcome to the Advanced Quantum-Nano Materials & Optoelectronics Laboratory (AQNMOL) !
AQNMOL is dedicated to exploring the potentials of advanced optoelectronic and functional devices and technologies that consume less energy, produce energy, offer higher performance & efficiency, i.e. photodetectors, sensors, energy generation, photovoltaics (PV) and light emitting diode (LEDs), etc. The advancement and development of energy saving & highly-efficient applications heavily reply on the improvement of novel quantum- and nano-structures and associated material systems.
AQNMOL focuses on the fabrication & characterization of advanced quantum- and nano-structures and materials & related device applications by unique Physio-Chemical approaches combining both the physical vapor deposition (PVD) of the pulsed laser deposition (PLD), sputtering, rapid thermal process (RTP) and chemical solution-based synthesis of the spin coating, electrochemical and potentiostat. Physicochemical research utilizes the advantages of both physical and chemical synthesis and fabrication and can offer advanced hybrid nanostructures and devices.
The characterizations utilize various equipment such as atomic force microscope (AFM), scanning electron microscope (SEM), energy dispersive x-ray spectroscope (EDS), Raman, photoluminescence (PL), UV-VIS spectroscopy, I-V (Photoresponse) measurements, X-ray diffraction (XRD) spectroscopy, X-ray photoelectron spectroscopy (XPS), electrochemical analysis and fabrications (CV, CA, LSV and EIS), simulations using finite-difference time domain (FDTD), Origin, Sigma plot, etc.

the important thing in life is not the triumph but the struggle,
the essential thing is not to have conquered but to have fought well.”
