Electrically Switchable White Light Laser Based on a Conjugated Photonic Bandgap Device
The supercontinuum generation with a broad pedestal spectrum has known to be a way to realize white light laser source. However, this white light laser source limits its application in some cases. In this study, a discrete white-light laser source based on a conjugated photonic crystal (CPC) is proposed. The CPC is composed of a photonic crystal (PC) infiltrate a layer of a dye-doped cholesteric liquid crystal (CLC). With a sole optical pump, the trichromatic laser can be induced and, through the CLC regulated by an applied voltage, the CPC structure can be electrical tunable in laser wavelength. The three lasing peaks originate from the two band edges of the CLC reflection band as well as one of the photonic defect modes as dual-mode lasing. According to the optically bistable property of CLC, such a white-light laser device can operate in low energy consumption. This technique has potential to be a new white-light source.

Improving mobility of photo-patterned sol-gel IGZO TFT by DUV exposure control
We investigate the key in photo-patterned sol-gel IGZO film by using DUV lamp. The DUV exposure time is found to be critical to influence film composition. With short DUV exposure and the following 300C DUV/thermal simultaneously annealing, the direct-write IGZO TFT exhibits mobility as high as 5.3 cm2/Vs.

Enhanced conductivity of PEDOT: PSS electrode by doping and dropping process with polar aprotic solvents for ITO-free organic light emitting diodes
We use the polar aprotic solvents to treat the PEDOT:PSS solution and film by heat treatment and doping. The films with different treatment were investigated and compared with each other in the difference of optical conductivity, transmittance, work function, surface roughness, surface morphology, and stability.

Complementary Logic Inverters Composed of N-Channel ZnO and P-Channel SnO Thin-Film Transistors
In this paper, complementary logic inverters consisting of zinc oxide (ZnO) and tin monoxide (SnO) thin-film transistors (TFTs) are demonstrated on rigid glass and flexible plastic foil substrates. Voltage gains of 13 V/V and 4.5 V/V are achieved for on-glass and on-plastic inverters, respectively.

Enhancing Optical Out-coupling of Organic Light-Emitting Devices with Nanostructured Composite Electrodes Consisting of Indium Tin Oxide Nanomesh and Conducting Polymer
A nanostructured composite electrode consisting of the high-index indium-tin-oxide nanomesh and low-index high-conductivity conducting polymer effectively enhances coupling of internal radiation of organic light-emitting devices into their substrates. When combining this internal extraction structure and the external extraction scheme, a very high external quantum efficiency of nearly 62% was achieved with a green phosphorescent device.
