Abstract:
|
In this paper we investigate the infrared thermal emission properties of macroporous silicon with
modulated pore diameter. Samples with different pore modulation periodicities but fixed in-plane
lattice constant are fabricated. Normal emission of these samples is measured between 373 and
673 K. Room-temperature normal-incidence reflectance and transmission spectra are also measured
and compared with the photonic band structure simulation. It is shown that thermal emission is
suppressed due to photonic band gap effect along the pore axis in excellent agreement with the
numerical calculations. |
