Abstract :
MBE-grown quantum dots of HgSe:Fe were investigated by infrared magnetotransmission using the single-turn-coil technique to generate megagauss fields. Due to the inhomogeneity of the dot size a broad absorption of the 10.6 /spl mu/m radiation is observed beyond the 2D cyclotron resonance at higher fields.
