Tunable topological phase transition in the telecommunication wavelength by Tian, Fanglin, Zhou, Junxiao, Wang, Qiang, Liu, Zhaowei

“…In this work, we propose a highly tunable topological phase transition based on valley photonic crystals. The topological phase transition is realized by the inversion symmetry broken due to the refractive index change of structures consisting of optical phase change material (OPCM) with thermal excitation of different sites in a honeycomb lattice structure. …”

Smart window for tuning transparency and noise absorption by Shrestha, Milan

“…For example, an optical smart window based on polymer dispersed liquid crystals (PDLC) ages when exposed to UV for years; an electrochromic window is pricey and prone to leakage; micro-perforated glass absorbers are only effective to absorb mid-frequency sound over a moderate bandwidth. …”

Fiber optic technique for determination of moisture content in honey by Mohamad Ibrahim, Nursakinah

“…However, for all other wavelengths, only polynomial second order relationships were found to give good regression coefficients due to crystallization of honey. Calibration equations have been established to predict moisture content in honey based on absorption measurement. …”

Terahertz conductivity of topological surface states in Bi1.5Sb0.5Te1.8Se1.2 by Tang, Chi Sin, Xia, Bin, Zou, Xingquan, Chen, Shi, Ou, Hong-Wei, Wang, Lan, Rusydi, A., Zhu, Jian-Xin, Chia, Elbert E. M.

“…Recently, a new topological insulator Bi1.5Sb0.5Te1.7Se1.3 (BSTS) was found, showing high bulk resistivities of 1–10 Ω.cm and greater contrast between the bulk and surface resistivities compared to other Bi-based topological insulators. Using Terahertz Time-Domain Spectroscopy (THz-TDS), we present complex conductivity of BSTS single crystals, disentangling the surface and bulk contributions. …”

Design, characterization and properties of nitrogen-containing novel organic N-type materials by Wu, Yuechao.

“…Although a lot of n-type organic materials have been reported,this research will specially focus on N-substituted polycyclic aromatic hydrocarbons(PAHs)because Houk et al predicted that the azaacenes have high electron affinities and could be promising candidates for n-type semiconducting materials.In fact,some N-heteroacenes have already shown decent electron mobility.Moreover,N-heteroacenes are more stable(resistive to oxidation or dimerization).In addition,the physical properties of n-substituted heteroacenes strongly depend on the number,position and valence states of nitrogen atoms.These progresses strongly encourage me to prepare larger azaacenes In this thesis,I have designed,synthesized and characterized several new azaacenes,which are expected to exhibit good performance in electronic devices.I developed a simple and efficient method(one or two steps)to prepare targeted azaacenes through condensation reaction starting from commercially available materials.All as-prepared compounds are very stable and have lower bandgaps.Phototransistors based on 6,8,15,17-tetraaza-1.18,4.5,9.10,13.14- tetrabenzoheptacene(TTP)single crystals have been fabricated and this device exhibited excellent performance in amplifying and converting light signal under the photoconductive effect.In addition,9,11,13,22,24,26-hexaza-tetrabenzo[a,c,l,n]heptacene(HATBH)can act as an efficient anion sensor for naked-eye detection of F- and H2PO4- anions and 9,26-dihydro 9,11,13,22,24,26-hexaza-tetrapyrido[3,2-a: 2’,3’-c:3”,2”-l:2”’,3”’-n]heptacene(DHATPH)can selectively sense F- anion among TEN anions(F-,Cl-,Br -,I-,PF6-,HSO4-,NO3-,BF4-,AcO-,and H2PO4-). …”
