아래의 기술중 저의 나라..삼성전자나 LG에서 가장 필요로 한 기술은 어떤건지 가르쳐 주시면 감사하겠습니다. 제가 전공할려고 관심을 가지는 분야인데 아직 미전공자로써 모두가 비슷하게 보이네요... 혹씨 이쪽 분야 전문가이신 분이 있으면 많은 조언 부탁드립니다. 1. Spatial light modulator (SLM) and microdisplay design and fabrication. We are looking for students to undertake the design and fabrication of new SLM technology. The recent availability of submicron foundry services with six metal planarised CMOS and optical quality top layer metal for mirrors has created a whole new area of research on intelligent pixel designs. These include applications in multimedia and portable hand-held device displays as well as optical switching and telecommunications devices. This research may include either cleanroom fabrication of devices within the group or silicon VLSI design, simulation and layout 2. Photo-luminescent displays. We have been developing a new display technology within the group, combining photo-luminescent phosphors and flat panel liquid crystal displays. There are several programs running within the group at the moment including liquid crystal characterisation, optical tiling and in-cell phosphor devices 3. Liquid crystal elect-optic effects. We are always looking to push back the boundaries on liquid crystal structures in both speed and electro-optic effects. Many of the applications we are currently researching could benefit from new, enhanced, specialised liquid crystal (or some other type) effects. 4. Ferroelectric liquid crystals for display applications It has recently been reported that the low molar mass dimeric organosiloxane liquid crystals display both ferroelectric and antiferroelectric behaviour depending only on the length of the siloxane spacer. The monomeric materials exhibit ferroelectric behaviour over the whole of the mesophase and have quite high spontaneous polarisation. The smectic tilt angles are independent of temperature and close to 45 degrees. The dimeric low molar mass organosiloxane materials exhibit either ferroelectric or antiferroelectric behaviour dependant upon the number of silicon atoms in the siloxane spacer and the lateral halogen substituent. For materials with 3 units in the siloxane chain the phase behaviour is purely antiferroelectric regardless of the nature of the halogen substituent. The spontaneous polarisation is of the order of 100 nC/sq. cm and the tilt angle is close to 45 degrees and independent of temperature. The antiferroelectricity is attributed to the siloxane moiety conferring a bent conformation on the molecule rather than antiferroelectric interactions between the layers. As these materials posses some of the robust mechanical properties of polymers, as well as the perfect bistability and fast electro-optic response of low molar mass liquid crystals, they make ideal candidates for use in ferroelectric or antiferroelectric devices.
