Surface Improvement of InAlAs/InGaAs InP-Based HEMT Through Treatments of UV/Ozone and TMAH
IEEE Journal of the Electron Devices Society, 2020 In this paper, we introduce novel surface treatments of UV/Ozone and TMAH to solve the surface problem of gate recess of InAlAs/InGaAs InP-based HEMTs. The problem of nonstoichiometric surface of InP etch stopper layer was found to be the result of donor-

Non-Invasive Determination of the Mass Flow Rate for Particulate Solids Using Microwaves
Sensors, 2023 This paper presents a novel technique for the mass flow rate determination of particulate solids called the “Sliding Mass Technique”. The mass flow rate is a measure of the mass of a substance that passes through a given cross-sectional area per unit ...

High-frequency nanotube mechanical resonators [PDF]
, 2012 We report on a simple method to fabricate high-frequency nanotube mechanical resonators reproducibly. We measure resonance frequencies as high as 4.2 GHz for the fundamental eigenmode and 11 GHz for higher order eigenmodes.

Seeding-Layer-Free Deposition of High-k Dielectric on CVD Graphene for Enhanced Gate Control Ability
Crystals, 2022 The gate insulator is one of the most crucial factors determining the performance of a graphene field effect transistor (GFET). Good electrostatic control of the conduction channel by gate voltage requires thin gate oxides.
