Development of polarization modulator using MXene thin film

Abstract

In this work, polarization modulator utilizing MXene material, namely Nb2C is demonstrated. S band signal is injected into Nb2C thin film and is modulated by 1400 nm laser diode. A total of 39.81° of polarization rotation is attained when the pump power is increased to 223 mW. The rotation of light is due to thermo-optic effect. The efficiency of polarization modulator is calculated at 0.1974°/mW.

Nb2CTx/Protonated Carbon Nitride Nanocomposite for Electrochemical Detection of Serotonin

“…Additionally, the peaks at 33.68°, 38°, and 60° corresponding to the (100), (103), and (110) planes of Nb 2 CT x , respectively, confirm the formation of MXenes . The XRD pattern of the Nb 2 CT x /PCN composite shows all the peaks for Nb 2 CT x and CN, which confirms the formation of the composite . However, the (002) peak of Nb 2 CT x is diminished and it can be due to the coverage of PCN on the surface of Nb 2 CT x …”

“…These characteristic diffraction peaks appear at the same positions after treatment with hydrochloric acid in PCN, indicating the well-preserved layered structure of polymeric CN after protonation. The XRD pattern of Nb 2 CT x exhibits the characteristic (002) peak at a diffraction angle of 9.3°, which clearly indicates the presence of layered Nb 2 CT x sheets . Additionally, the peaks at 33.68°, 38°, and 60° corresponding to the (100), (103), and (110) planes of Nb 2 CT x , respectively, confirm the formation of MXenes .…”

High electrolyte uptake of MXene integrated membrane separators for Zn-ion batteries

“…Typically, MXene is synthesized from the phase (MAX phase), where M is a transition metal, A refers to a IIIA or IVA element, X represents carbon or nitrogen atoms, and n = 1, 2, 3 integers. Therefore, different MXene chemical structures, including Ti 3 C 2 T x 17 – 19 , Ta 4 C 3 20 , 21 , Nb 2 C 22 – 24 , and ZrC 25 , 26 , are available. Ti 3 C 2 has been used widely.…”
