Low-Temperature Optical Characterization of Single CdS Nanowires
L. V. Titova, Thang B. Hoang, H. E. Jackson +4
We use spatially resolved micro-PL imaging at low temperature to study optical properties of two sets of CdS nanowires grown using 20 nm and 50 nm catalysts. We find that low tempe…
Temperature dependent photoluminescence of single CdS nanowires
Thang Ba Hoang, L. V. Titova, H. E. Jackson +4
Temperature dependent photoluminescence (PL) is used to study the electronic properties of single CdS nanowires. At low temperatures, both near-band edge (NBE) photoluminescence (P…
Low temperature photoluminescence imaging and time-resolved spectroscopy of single CdS nanowires
L. V. Titova, Thang Ba Hoang, H. E. Jackson +4
Time-resolved photoluminescence (PL) and micro-PL imaging were used to study single CdS nanowires at 10 K. The low-temperature PL of all CdS nanowires exhibit spectral features nea…
Perpendicular magnetization reversal, magnetic anisotropy, multi-step spin switching, and domain nucleation and expansion in Ga1-xMnxAs films
X. Liu, W. L. Lim, L. V. Titova +4
We present a comprehensive study of the reversal process of perpendicular magnetization in thin layers of the ferromagnetic semiconductor Ga1-xMnxAs. For this investigation we have…
External control of the direction of magnetization in ferromagnetic InMnAs/GaSb heterostructures
X. Liu, W. L. Lim, L. V. Titova +10
In this paper, we demonstrate external control over the magnetization direction in ferromagnetic (FM) In_{1-x}Mn_{x}As/GaSb heterostructures. FM ordering with T_C as high as 50 K i…
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…
