Operation of Graphene Transistors at GHz Frequencies
Top-gated graphene transistors operating at high frequencies (GHz) have been fabricated and their characteristics analyzed. The measured intrinsic current gain shows an ideal 1/f frequency dependence, indicating an FET-like behavior for graphene transistors. The cutoff frequency fT is found to be proportional to the dc transconductance gm of the device, consistent with the relation fT=gm/(2πCG)...
متن کاملSingle carbon nanotube transistor at GHz frequency.
We report on microwave operation of top-gated single carbon nanotube transistors. From transmission measurements in the 0.1-1.6 GHz range, we deduce device transconductance gm and gate-nanotube capacitance Cg of micro- and nanometric devices. A large and frequency-independent gm approximately 20 microS is observed on short devices, which meets the best dc results. The capacitance per unit gate ...
متن کاملFeasibility Study for Non-Contact Heartbeat Detection at 2.4 GHz and 60 GHz
Two new schemes for human non-invasive cardiopulmonary activity monitoring are demonstrated using microwave low power and non-contact Doppler sensors. The two systems, using direct conversion architecture and simple design, are demonstrated and tested at a distance of 1 m from the patient. The first one proposes a simple technique for direct measurement of heartbeat signal at 2.4 GHz while the ...
متن کاملEffect of Microwave Wi-Fi Radiation at Frequency of 2.4 GHz on Epileptic Behavior of Rats
Background: Electromagnetic fields (EMF) with different intensities are widely used at home, offices and public places.Today, there is a growing global concern about the effects of human exposure to EMFs. Epilepsy is one of the most common chronic neurological diseases, affecting 50 million people of all ages worldwide. We aimed to investigate the effect of exposure to Wi-Fi radiation on epilep...
متن کاملFrequency of contact sensitivity in patients with contact or Atopic Dermatitis with Patch test
Background and aim: Eczema is a common inflammatory skin disease. Although history and physical examination are important in diagnosis of allergen, because of extent of environmental allergens, those are not simply recognized. The objective of this study was to determine allergens in patients with contact or atopic dermatitis referred to Razi hospital.Materials and Meth...
