Diluted II-VI Oxide Semiconductors with Multiple Band Gaps
K. M. Yu, W. Walukiewicz, J. Wu +5
We report the realization of a new multi-band-gap semiconductor. The highly mismatched alloy Zn1-yMnyOxTe1-x has been synthesized using the combination of oxygen ion implantation a…
Growth and properties of ferromagnetic In(1-x)Mn(x)Sb alloys
T. Wojtowicz, W. L. Lim, X. Liu +15
We discuss a new narrow-gap ferromagnetic (FM) semiconductor alloy, In(1-x)Mn(x)Sb, and its growth by low-temperature molecular-beam epitaxy. The magnetic properties were investiga…
Enhancement of Curie temperature in Ga(1-x)Mn(x)As/Ga(1-y)Al(y)As ferromagnetic heterostructures by Be modulation doping
T. Wojtowicz, W. L. Lim, X. Liu +6
The effect of modulation doping by Be on the ferromagnetic properties of Ga(1-x)Mn(x)As is investigated in Ga(1-x)Mn(x)As/Ga(1-y)Al(y)As heterojunctions and quantum wells. Introduc…
Structural and Electronic Properties of Amorphous and Polycrystalline In2Se3 Films
A. Chaiken, K. Nauka, G. A. Gibson +6
Structural and electronic properties of amorphous and single-phase polycrystalline films of gamma- and kappa-In2Se3 have been measured. The stable gamma phase nucleates homogeneous…
Fundamental Curie temperature limit in ferromagnetic GaMnAs
K. M. Yu, W. Walukiewicz, T. Wojtowicz +5
We provide experimental evidence that the upper limit of ~110 K commonly observed for the Curie temperature T_C of Ga(1-x)Mn(x)As is caused by the Fermi-level-induced hole saturati…
In(1-x)Mn(x)Sb - a new narrow gap ferromagnetic semiconductor
T. Wojtowicz, G. Cywinski, W. L. Lim +10
A narrow-gap ferromagnetic In(1-x)Mn(x)Sb semiconductor alloy was successfully grown by low-temperature molecular beam epitaxy on CdTe/GaAs hybrid substrates. Ferromagnetic order i…
