Quantum size effects on surface states of TiO2 ultrafine
1). This phenomenon may be due to Ultrafine Particles Mu- 1 in different diameter circle fit,) UFP of the SPS Relative phase angle (A). It said samples from the beginning of light shines on the surface of the largest photovoltaic response time interval ,[link widoczny dla zalogowanych], Figure 4 shows a cell modulated light pulse and lock angle. Start illumination (A point ) phase is zero. Although this time the photon penetration depth of a hole has been on a lot of e- generation, but only from the surface of the carrier mean free path ( Si ) optical depth of carriers migrate to the surface voltage will appear neodymium big time Value. A and materials related to the holder of the material properties . A & L, the surface barrier height , carrier mobility and optical penetration depth and so on. Material over pier size fnln) Figure 3 Relationship between particle size and phase ABAII; 7F a .180 Light pulse and lock your system , some relationship between the phase A: Start light , H; stop light technology , the particle size close to or less than the time. Particle size has a great influence on A , which is super- pier effect of quantum particles . 1l4
