Strain-engineered SiGe nanomembrane quantum-well infrared photodetectors
(Ieee, 2017)
SiGe quantum-well nanomembranes, where stress from lattice mismatch is relaxed via elastic strain sharing rather than defect formation, are used to develop intersubband photodetectors showing improved performance compared ...
Theoretical study of thermoelectric properties of p-type Mg-2 Si1-chi Sn-chi solid solutions doped with Ga
(Elsevier Science Sa, 2017)
Mg-2 Si-Mg-2 Sn solid solutions are a promising class of thermoelectric materials. the thermoelectric properties of p-type Mg-2(Si-0.3 Sn-0.7)(1-y) Gay solid solutions with the doping levels as y = 0.05 and y = 0.07 are ...
Thermoelectric properties of Mg2X (X = Si, Ge) based bulk and quantum well systems
(Amer Inst Physics, 2017)
Mg2X (X = Si, Ge) compounds are promising thermoelectric materials for middle temperature applications due to good thermoelectric properties, nontoxicity, and abundantly available constituent elements. So far, these materials ...
III-nitride terahertz photodetectors for the reststrahlen gap of intersubband optoelectronics
(Spie-Int Soc Optical Engineering, 2017)
We report the development of terahertz intersubband photodetectors based on GaN/AlGaN quantum wells, covering the frequency range that is fundamentally inaccessible to existing III-V semiconductor devices due to Reststrahlen ...
Classification of EEG based BCI signals imagined hand closing and opening
(Ieee, 2017)
Brain-computer interfaces allow people to manage electronic devices such as computers without using their motor nervous system. When the brain is in a function, nerve cells in the brain communicate with each other with ...
Graphene terahertz plasmons: A combined transmission spectroscopy and raman microscopy study
(Amer Chemical Soc, 2017)
Graphene provides a promising materials platform for fundamental studies and device applications in plasmonics. Here we investigate the excitation of THz plasmon polaritons in large-area graphene samples on standard oxidized ...
The design steps of a hybrid energy system
(Polish Acad Sciences Inst Physics, 2017)
In this paper the design stages of a mixed photovoltaic-wind energy system, supplied with solar and wind energy was discussed. First, general information about the employed wind turbines and solar panels is given and their ...
Investigation of GSM, LTE and Wi-Fi electromagnetic radiation in dwellings
(Polish Acad Sciences Inst Physics, 2017)
Electromagnetic radiation exposure increases with the rise of the wireless communication devices. Electromagnetic radiation, especially near 2400 MHz band, has gradually increased with the widespread of wireless fidelity ...
OFDM performance of ultra wideband in wireless body area network channel
(Polish Acad Sciences Inst Physics, 2017)
Data transfer for health monitoring can be highly critical because of life dependency transmitted data. IEEE 802.15.6 is a standard for wireless body area network published in 2012 to satisfy the reliability which is ...
Remote leak hole localization for underwater natural gas pipelines
(Ieee, 2017)
A vast amount of natural gas pipelines are installed underwater and they can be punctured because of various reasons such as corrosion and their increasing ages. in this study, nature of acoustic signals which are generated ...
